[0008] 依據本說明書及添附圖面的記載，至少可使以下的事項更明確。 本創作為一種吸收性物品，係具有長度方向、寬度方向及厚度方向，且具備有吸收性芯材之吸收性物品，其特徵為，在非肌膚側面設有黏著區域，在較前述長度方向的至少一方側之前述黏著區域的端部更靠近前述長度方向之外側、且前述寬度方向的兩端部，設有前述吸收性芯材朝前述厚度方向凹陷之第1凹部及第2凹部，在前述第1凹部及前述第2凹部，比起鄰接區域，前述吸收性芯材的密度較高，前述第1凹部與前述第2凹部係在前述寬度方向上分離。 [0009] 若依據這樣的吸收性物品，藉由第1凹部及第2凹部，可使吸收性芯材的角部之剛性提高。因此，當往上提起內褲時，未固定於內褲之吸收性芯材的角部不易傾倒且不易彎折。因此，吸收性芯材的角部不會扭曲或彎折，容易適當地進行穿戴吸收性物品。又，由於第1凹部與第2凹部在寬度方向上分離，故，長度方向上之吸收性物品的端部區域不易固定為平面狀。因此，端部區域容易沿著穿用者的下腹部、臀部等彎曲，貼身性佳。 [0010] 在該吸收性物品，其中，前述第1凹部及前述第2凹部係在前述寬度方向上，設在較前述黏著區域的端部更外側。 [0011] 若依據這樣的吸收性物品，能夠提高當往上提起內褲時容易傾倒、彎折之吸收性芯材的角部之剛性。 [0012] 在該吸收性物品，其中，於前述第1凹部與前述第2凹部之間，設有前述吸收性芯材的基重較鄰接區域低之低基重區域。 [0013] 若依據這樣的吸收性物品，長度方向上之吸收性物品的端部區域容易沿著穿用者的下腹部、臀部等彎曲，貼身性佳。 [0014] 在該吸收性物品，其中，在前述第1凹部與前述第2凹部之間，設有一對前述低基重區域，在前述長度方向上較前述黏著區域的端部更外側且一對前述低基重區域之間，設有前述吸收性芯材朝前述厚度方向凹陷之第3凹部，在前述第3凹部，比起鄰接區域，前述吸收性芯材的密度較高。 [0015] 若依據這樣的吸收性物品，藉由第3凹部，使一對低基重區域之間的剛性提高，當往上提起內褲時不易傾倒且不易彎折。因此，吸收性芯材不會扭曲或彎折，容易適當地進行穿戴吸收性物品。 [0016] 在該吸收性物品，其中在前述低基重區域的前述寬度方向之兩側，設有前述黏著區域。 [0017] 若依據這樣的吸收性物品，由於以低基重區域區劃的吸收性芯材之區域的基底部分固定於內褲，且在較黏著區域更靠近長度方向的外側設有第1凹部、第2凹部等，故，吸收性芯材不易扭曲或彎折，可適當地進行穿戴。 [0018] 在該吸收性物品，其中，前述第1凹部及前述第2凹部係為線狀的凹部，在平面視角，前述第1凹部及前述第2凹部各自的一部分是與前述黏著區域重複。 [0019] 若依據這樣的吸收性物品，藉由第1凹部及第2凹部，自固定於內褲的部位起連續，使得吸收性芯材的角部之剛性提高。因此，吸收性芯材的角部不會扭曲或彎折，容易進行穿戴吸收性物品。 [0020] 在該吸收性物品，其中，在平面視角，前述第1凹部及前述第2凹部各自的一端部及另一端部是與前述黏著區域重複。 [0021] 若依據這樣的吸收性物品，藉由第1凹部及第2凹部，自固定於內褲的2個部位起連續，使得吸收性芯材的角部之剛性提高。因此，吸收性芯材的角部不會扭曲或彎折，容易進行穿戴吸收性物品。 [0022] 在該吸收性物品，其中，前述凹部係為線狀的凹部，具有從前述長度方向的外側朝中央側折返之折返部。 [0023] 若依據這樣的吸收性物品，設有第1凹部及第2凹部之區域變大，使得吸收性芯材的角部之剛性提高。又，折返部係具有長度方向的成分與寬度方向的成分，被折返部所包圍的區域容易維持平面形狀。因此，吸收性芯材的角部不會扭曲或彎折，容易適當地進行穿戴吸收性物品。 [0024] 在該吸收性物品，其中，在前述長度方向上與前述第1凹部及前述第2凹部重複的前述吸收性芯材之部位係其輪廓呈凹凸形狀，並具有預定數量的突出部，前述第1凹部及前述第2凹部係為沿著前述吸收性芯材的輪廓之線狀的凹部，且具有前述預定數量的突出部。 [0025] 若依據這樣的吸收性物品，藉由第1凹部及第2凹部沿著吸收性芯材的輪廓，可容易對使用者賦予藉由第1凹部及第2凹部的內側之膨脹所產生的穿戴性佳的印象、具有高級感的印象等。又，藉由吸收性芯材的輪廓作成凹凸形狀，使得當吸收性芯材因應穿用者的動作變形時，能夠以突出部之間的谷部作為起點進行彎折而使皺紋的產生變得一致，能夠抑制無秩序的皺紋產生。 [0026] 在該吸收性物品，其中，在前述長度方向的兩側分別設有前述第1凹部及前述第2凹部，前述長度方向的前側之前述第1凹部及第2凹部係在前述長度方向上，與前述長度方向上的後側之前述第1凹部及前述第2凹部分離。 [0027] 若依據這樣的吸收性物品，吸收性芯材的4個角部不會扭曲或彎折，容易適當地進行穿戴吸收性物品。又，能夠防止吸收性物品在長度方向的中央區域之寬度方向的側部的立起傳達至長度方向的端部區域，使得端部區域容易沿著穿用者的下腹部、臀部等彎曲，貼身性佳。 [0028] 在該吸收性物品，其中，還具備有朝前述寬度方向延伸之一對翼部，在較前述翼部更靠近前述長度方向的外側且在前述吸收性芯材的前述寬度方向之兩端部，設有前述吸收性芯材的基重較鄰接區域低之一對第2低基重區域。 [0029] 若依據這樣的吸收性物品，能夠防止吸收性物品在長度方向的中央區域之寬度方向的側部的立起傳達至長度方向的端部區域，使得端部區域容易沿著穿用者的下腹部、臀部等彎曲，貼身性佳。 [0030] 以下，作為本創作的吸收性物品，以生理用衛生棉為例，說明實施形態。但，不限於此，本創作亦可適用於例如分泌物用薄片、尿液吸收墊等的其他吸收性物品。 [0031] ===生理用衛生棉1的基本結構=== 圖1係從肌膚側觀看生理用衛生棉1(以下稱為衛生棉)之平面圖。圖2係從非肌膚側觀看衛生棉1之平面圖。圖3A係圖1中的AA線之衛生棉1的示意斷面圖。圖3B係用來說明點狀壓榨部6及線狀壓榨部40之衛生棉1的示意斷面圖。 [0032] 衛生棉1係具有相互正交之長度方向、寬度方向及厚度方向。在長度方向，將抵接於穿用者的下腹部之側稱為前側，抵接於穿用者的臀部之側稱為後側。在厚度方向，將抵接於穿用者之側稱為肌膚側，將其相反側稱為非肌膚側。 [0033] 如圖3A所示，在衛生棉1，從厚度方向的肌膚側起依序層積有一對側薄片2、頂面薄片3、第2薄片4、吸收體10及背面薄片5。該等各構件2~5、10係以未圖示的接著劑，來與在厚度方向上相鄰接的構件接合。再者，頂面薄片3及第2薄片4係為透液性的薄片，可舉出例如熱風不織布等。背面薄片5係為不透液性的薄片，可舉出例如聚乙烯(PE)的樹脂薄膜等。頂面薄片3及背面薄片5係平面尺寸較吸收體10大，用以覆蓋吸收體10的平面全體。 [0034] 衛生棉1係具有：設有吸收體10的衛生棉本體部20；及從衛生棉本體部20的長度方向中央區域朝寬度方向的兩外側延伸伸出之一對翼部30。翼部30係藉由從頂面薄片3的寬度方向之兩側部朝外側延伸伸出之側薄片2及背面薄片5所形成。再者，衛生棉1亦可為不具有翼部30之形態。 [0035] 在衛生棉1，將較翼部30更靠近長度方向的前側之區域稱為前側區域R1，將設有翼部30之區域稱為中央區域R2，將較翼部30更靠近長度方向的後側之區域稱為後側區域R3。衛生棉1係藉由位於前側區域R1之前側折疊部Ff和位於後側區域R3之後側折疊部Fb作成3折而個別包裝。 [0036] 在衛生棉本體部20的非肌膚側面(背面薄片5的非肌膚側面)，設有塗佈有接著劑等之黏著區域21。當使用衛生棉1時，黏著區域21被黏貼於內褲等的肌膚側面，藉此，衛生棉1固定於內褲等。在圖2中，沿著長度方向具有長邊之長方形狀的3個黏著區域21係在長度方向上隔著間隔排列，並且該3個黏著區域21的列係在寬度方向上隔著間隔排列有8列，但，黏著區域21的形狀、數量不限於此。 [0037] 同樣地，在各翼部30的非肌膚側面(背面薄片5的非肌膚側面)，設有翼部用黏著區域31。當使用衛生棉1時，翼部用黏著區域31被黏貼於內褲等的非肌膚側面，藉此，衛生棉1固定於內褲等。在圖2中，沿著長度方向具有長邊之長方形狀的2個翼部用黏著區域31係排列於寬度方向上，但，翼部用黏著區域31的形狀、數量不限於此。 [0038] 吸收體10係為吸收排泄物並保持在內部之構件，如圖3A所示，具有：吸收性芯材12；位於較吸收性芯材12更靠近肌膚側之肌膚側薄片11；位於吸收性芯材12更靠近非肌膚側之非肌膚側薄片13。 [0039] 吸收性芯材12係對吸液性纖維之紙漿纖維、纖維素系吸收性纖維等，添加吸液性粒狀物之高吸收性聚合物(所謂的SAP)等，再形成為預定形狀者。肌膚側薄片11係為透液性的薄片，可舉出例如薄紙等。非肌膚側薄片13，可為透液性的薄片，亦可為不透液性的薄片，可舉出例如薄紙等。吸收性芯材12、肌膚側薄片11及非肌膚側薄片13係為大致相同形狀的平面形狀，藉由接著劑(未圖示)接合成從肌膚面側及非肌膚面側分別覆蓋吸收性芯材12。 [0040] 雖未圖示，在吸收體10，遍及其平面全區域，均等地設有複數個吸收體點狀壓榨部14。在吸收體點狀壓榨部14，如圖3B所示，吸收體10朝厚度方向被壓榨(壓花加工)而朝厚度方向凹陷，比起鄰接區域，吸收性芯材12的密度變高。藉由吸收體點狀壓榨部14，吸收體10的剛性提高，使得排泄物等容易朝長度方向擴散。 [0041] 在衛生棉1的肌膚側面，如圖1所示，設有複數個點狀壓榨部6及複數個線狀壓榨部40。在點狀壓榨部6及線狀壓榨部40，如圖3B所示，頂面薄片3、第2薄片4及吸收體10朝厚度方向的肌膚側被壓榨而凹陷，比起鄰接區域，吸收性芯材12的密度變高。 [0042] 複數個線狀壓榨部40係沿著吸收性芯材12的輪廓進行設置。複數個點狀壓榨部6係在設置於衛生棉1的中央區域R2之寬度方向的兩側部之一對線狀壓榨部40之間，以隔著較大的間隔而排列成鋸齒狀的方式設置。 [0043] ===關於吸收體10=== 圖4係用來說明吸收體10之衛生棉1的平面圖。 在吸收體10的寬度方向之中央部，設有沿著長度方向之折疊誘導部15。在折疊誘導部15，如圖3B所示，吸收體10從厚度方向的非肌膚側被壓榨而凹陷，比起鄰接區域，吸收性芯材12的密度變高。藉由折疊誘導部15，吸收體10變得容易沿著長度方向彎折成朝肌膚側突出，變得容易密接於穿用者的排泄口(陰道口)。因此，至少在衛生棉1的長度方向之中央區域R2，設置折疊誘導部15為佳。 [0044] 再者，折疊誘導部15不限於藉由壓榨來形成。例如，亦可為藉由使吸收性芯材12的基重沿著長度方向降低，或在製造製程中，對吸收體10實施將吸收體10沿著長度方向折彎之加工，或沿著長度方向塗佈熱熔膠接著劑，形成折疊誘導部15。 [0045] 又，吸收性芯材12係具有：一對前側缺口部50；一對後側缺口部51；一對前側狹縫52；後側狹縫53；及前側空心部54。在該等部位50～54，不存在有吸收性芯材12，比起吸收性芯材12存在的區域，剛性較低。再者，在前述部位50～54，可存在或不存在肌膚側薄片11及非肌膚側薄片13皆可。 [0046] 一對前側缺口部50及一對後側缺口部51分別係為在較翼部30更靠近長度方向的外側、且吸收性芯材12的寬度方向之兩端部，吸收性芯材12被切削之部位。具體而言，吸收性芯材12被切削成朝寬度方向的內側成為凸狀之山形狀，但缺口的形狀不限於此。又，一對前側缺口部50(一對第2低基重區域)係設在前側區域R1中靠近中央區域R2(翼部30)之側，在長度方向上與個別包裝用前側折疊部Ff重複。一對後側缺口部51(一對第2低基重區域)係設在後側區域R3中靠近中央區域R2(翼部30)之側，在長度方向上與後側折疊部Fb重複。 [0047] 一對前側狹縫52係為從吸收性芯材12的前端朝內側，將吸收性芯材12細長地切削之部位，對縱中心線CL呈對稱地設置。縱中心線CL係沿著將衛生棉1朝寬度方向對分之長度方向的線。又，前側狹縫52係朝長度方向的中央側，向寬度方向的內側傾斜，設於較前側缺口部50更靠近長度方向的前側。 [0048] 後側狹縫53係為從吸收性芯材12的後端之寬度方向的中心朝內側，將吸收性芯材12沿著長度方向細長地切削之部位。後側狹縫53係在長度方向上延伸至與後側缺口部51重複之位置。 [0049] 前側空心部54係於在長度方向上與一對前側缺口部50重複的位置，將吸收性芯材12的寬度方向之中央部沿著寬度方向細長地切削之部位。 [0050] 具有前述結構的吸收性芯材12之衛生棉1係容易貼身於穿用者。因此，排泄物不易洩漏，能夠減輕穿戴衛生棉1的不舒服感，穿戴性佳。以下說明關於這一點。 [0051] 衛生棉1的中央區域R2係容易變形成剖面成為W字狀。具體而言，藉由折疊誘導部15，使寬度方向的中央部容易朝肌膚側突出，密接於穿用者的排泄口。又，受到內褲的腿洞之橡膠(鬆緊帶)的影響，寬度方向的兩側部朝肌膚側立起，包住穿用者的陰唇部。在衛生棉1的中央區域R2，設有點狀壓榨部6及線狀壓榨部40。因此，寬度方向的側部係剛性較高，不會有因穿用者的腳的挾持力造成崩潰，可朝肌膚側立起。 [0052] 衛生棉1的前側區域R1及後側區域R3，係容易以設有一對前側缺口部50及一對後側缺口部51之長度方向的位置作為起點立起。因此，衛生棉1容易變形為從穿用者的下腹部通過胯下部而到達臀部之形狀，可貼身於穿用者。 [0053] 又，衛生棉1的前側區域R1及後側區域R3，係藉由一對前側缺口部50及一對後側缺口部51，對中央區域R2變得容易扭曲(例如，以縱中心線CL為軸容易擺動)。因此，衛生棉1能夠追隨穿用者的各種動作，可維持著密接於穿用者之狀態。 [0054] 且，在長度方向上，一對前側缺口部50與前側空心部54及前側折疊部Ff重複。又，在長度方向上，一對後側缺口部51與後側折疊部Fb重複。因此，衛生棉1的前側區域R1及後側區域R3係對中央區域R2容易立起而變得容易扭曲。 [0055] 又，在一對前側缺口部50及一對後側缺口部51，衛生棉1的剛性低，容易變形。因此，在衛生棉1之在中央區域R2之寬度方向的側部之立起，被一對前側缺口部50及一對後側缺口部51遮斷。同樣地，在寬度方向上，後側狹縫53及前側空心部54係與折疊誘導部15重複。因此，在衛生棉1之在中央區域R2之寬度方向的中央部之立起，被後側狹縫53及前側空心部54遮斷。亦即，衛生棉1之在中央區域R2的W字狀的變形不易傳達至前側區域R1及後側區域R3，前側區域R1及後側區域R3變形為沿著穿用者的下腹部、臀部等彎曲的面形狀，貼身於穿用者。 [0056] 又，衛生棉1的前側區域R1係藉由一對前側狹縫52，容易彎曲而貼身成包住穿用者的下腹部(被所謂比基尼線包圍的倒三角形之部位)。又，當穿用者的腳合起，前述倒三角形的部位變小時，吸收性芯材12的剩餘部位可朝前側狹縫52迴避，能夠防止吸收性芯材12被折疊成皺巴巴。亦即，在前側狹縫52使頂面薄片3、背面薄片5被俐落地折疊，前側區域R1不會有間隙地貼身於穿用者的下腹部。 [0057] 同樣地，衛生棉1的後側區域R3係藉由後側狹縫53，容易沿著穿用者的臀部彎曲而貼身。又，後側狹縫53之兩側的吸收性芯材12獨立而容易動作。因此，即使在穿用者步行時等，左右的臀部之動作不同的情況，吸收性芯材12可分別追隨左側臀部與右側臀部，可容易維持密接於臀部之狀態。 [0058] 如此，在衛生棉1的前側區域R1及後側區域R3，如後側狹縫53，設有沿著縱中心線CL之狹縫，或如一對前側狹縫52，從縱中心線CL上的點呈放射狀設置複數個狹縫為佳。藉此，衛生棉1的前側區域R1及後側區域R3變得容易沿著穿用者的下腹部、臀部等。 [0059] 再者，在本實施形態，在一對前側缺口部50、一對後側缺口部51、一對前側狹縫52、後側狹縫53及前側空心部54，將吸收性芯材12的基重設為零。但不限於此，在前述部位50~54，亦可存在有吸收性芯材12，比起鄰接區域，吸收性芯材12的基重(每單位面積的質量[g／m2]))較低即可。在該情況，在前述部位50~54，比起其他區域，剛性變得較低，能夠獲得相同的效果。又，亦可為吸收性芯材12不具有前述部位50~54之形態。 [0060] 又，前述部位50~54與其鄰接區域之吸收性芯材12的基重之比較，可藉由習知的方法進行即可。例如，將對象部位作為樣品而從衛生棉1切出，再測定各樣品的質量與面積。然後，算出每單位面積的質量再進行比較之方法。再者，若比較樣品的條件相同的話，亦可進行肌膚側薄片11及非肌膚側薄片13接著於吸收性芯材12的狀態下之基重的比較。 [0061] ===關於線狀壓榨部40=== 圖5係用來說明設在前側區域R1之線狀壓榨部40的圖。圖6係用來說明設在後側區域R3之線狀壓榨部40的圖。如前述般，在衛生棉1的肌膚側面，沿著吸收性芯材12的輪廓設有複數個線狀壓榨部40，在衛生棉1的非肌膚側面，設有黏著區域21。在從圖4至圖6，在平面視角(朝厚度方向觀看)，線狀壓榨部40與黏著區域21以重複的方式被描繪。 [0062] 在本實施形態的衛生棉1，如圖4所示，比起黏著區域21的長度方向之端部21a，21b，吸收性芯材12的長度方向之端部12a，12b位於更靠近長度方向的外側。因此，吸收性芯材12的長度方向之兩端部係為不與黏著區域21重複，並未固定於內褲。 [0063] 因此，在未固定於內褲之吸收性芯材12的角部12A(以粗線顯示輪廓之部位)，設置線狀壓榨部40。具體而言，在長度方向上，於較黏著區域的端部21a，21b更外側、且寬度方向之兩端部(亦即，對縱中心線CL，為寬度方向的一方側及另一方側)，設置有「第1線狀壓榨部41(第1凹部)」及「第2線狀壓榨部42(第2凹部)」。又，在長度方向的兩側，分別設有第1線狀壓榨部41及第2線狀壓榨部42。 [0064] 再者，長度方向的前側之第1線狀壓榨部41A與前側之第2線狀壓榨部41B，係對縱中心線CL呈對稱的形狀，後側之第1線狀壓榨部41B與後側之第2線狀壓榨部42B係對縱中心線CL呈對稱的形狀，但，不限於此。再者，前側之第1線狀壓榨部41A及第2線狀壓榨部42A、與後側之第1線狀壓榨部41B及後側之第2線狀壓榨部42B，係不同形狀，但，不限於此。 [0065] 在線狀壓榨部40，如圖3B所示，吸收性芯材12朝厚度方向凹陷，比起吸收性芯材12未被壓榨之鄰接區域，吸收性芯材12的密度高。因此，在設有線狀壓榨部40之部位，剛性較高。故，吸收性芯材12的角部12A也藉由第1線狀壓榨部41及第2線狀壓榨部42使剛性變高，變得容易維持面形狀。因此，當為了穿戴衛生棉1而將黏貼有衛生棉1之內褲往上提起時，即使吸收性芯材12的角部12A未固定於內褲，也不易朝穿用者側傾倒或彎折。因此，當內褲經由衛生棉1密接於穿用者時，吸收性芯材12的角部12A不會扭曲或彎折，可容易適當地穿戴衛生棉1。 [0066] 換言之，若依據在吸收性芯材12的角部12A設有線狀壓榨部40之本實施形態的衛生棉1的話，即使黏著區域21之長度較短，亦可適當地穿戴衛生棉1。因此，可減少形成黏著區域21的接著劑之塗佈量，當進行個別包裝時，可縮小覆蓋黏著區域21的剝離紙，因此可減低成本。 [0067] 又，第1線狀壓榨部41與第2線狀壓榨部42係在寬度方向上分離，且不連續。因此，衛生棉1的前側區域R1及後側區域R3係不易固定成平面狀，柔順地動作，寬度方向之兩端部容易獨立地動作。因此，衛生棉1的前側區域R1、後側區域R3等沿著穿用者的下腹部、臀部等而容易彎曲。又，可分別追隨左側臀部與右側臀部，能夠維持密接於臀部之狀態。如以上所述，本實施形態的衛生棉1，可適當地穿戴，貼身性亦佳。 [0068] 又，第1線狀壓榨部41及第2線狀壓榨部42係在長度方向上設在較黏著區域21的端部21a、21b更外側且在寬度方向上設在較黏著區域21的端部21a、21b更外側。藉此，能夠在當內褲往上提起時容易傾倒且彎折之吸收性芯材12的角部12A，設置線狀壓榨部40。因此，能夠更確實地使吸收性芯材12的角部12A不會扭曲或彎折，容易穿戴衛生棉1。 [0069] 又，在長度方向的至少一方側，設置第1線狀壓榨部41及第2線狀壓榨部42即可，但，在長度方向的兩側分別設置第1線狀壓榨部41及第2線狀壓榨部42。藉此，可使吸收性芯材12的4個角部12A不會扭曲或彎折，容易穿戴衛生棉1。 [0070] 在該情況，前側之第1線狀壓榨部41A及第2線狀壓榨部42A、與後側之第1線狀壓榨部41B及第2線狀壓榨部42B連續的話，則會有衛生棉1在中央區域R2之寬度方向的側部的立起傳達到前側區域R1及後側區域R3之虞。因此，使前側之第1線狀壓榨部41A與後側之第1線狀壓榨部41B在長度方向分離，使前側之第2線狀壓榨部42A與後側之第2線狀壓榨部42B在長度方向上分離為佳。藉此，衛生棉1的前側區域R1及後側區域R3變得容易沿著穿用者的下腹部、臀部等，貼身性佳。 [0071] 又，在前側之第1線狀壓榨部41A與前側之第2線狀壓榨部42A之間，設有一對前側狹縫52，在後側之第1線狀壓榨部41B與後側之第2線狀壓榨部42B之間，設有後側狹縫53。如前述般，若在吸收性芯材12設置前側狹縫52、後側狹縫53(低基重區域)等的話，則可使衛生棉1之貼身性提升。 [0072] 另外，當往上提起內褲時，比起前側狹縫52、後側狹縫53等，寬度方向之外側的部位更容易傾倒或彎折。因此，如本實施形態的衛生棉1，在前側狹縫52、後側狹縫53等的寬度方向之外側的部位，亦即，在吸收性芯材12之角部12A，設置第1線狀壓榨部41、第2線狀壓榨部42等更為有效。 [0073] 又，不僅吸收性芯材12的角部12A，一對前側狹縫52之間的吸收性芯材12的部位12B也會有當穿戴衛生棉1時傾倒或彎折之虞。因此，在長度方向上較黏著區域的端部21a更前側(外側)，且於一對前側狹縫52之間，設置線狀壓榨部40(以下亦稱為第3線狀壓榨部43(第3凹部))為佳。藉此，一對前側狹縫52之間的吸收性芯材12的部位12B之剛性提高，變得容易維持面形狀。因此，一對前側狹縫52之間的吸收性芯材12的部位12B不會扭曲或彎折，容易穿戴衛生棉1。 [0074] 又，第3線狀壓榨部43係在寬度方向上與第1線狀壓榨部41分離，在寬度方向上亦與第2線狀壓榨部42分離為佳。藉此，以一對前側狹縫52所區劃之吸收性芯材12的3個領域12A，12B可獨立容易動作，衛生棉1之前側區域R1容易沿著穿用者之下腹部彎曲。 [0075] 再者，在線狀壓榨部40(第1凹部、第2凹部、第3凹部)，至少吸收性芯材12之一部分被壓榨即可，不限於如本實施形態所示，從頂面薄片3進行壓榨。又，在本實施形態的線狀壓榨部40，複數個點狀壓榨部以狹窄的間隔排列成線狀，線狀壓榨部40的平均之吸收性芯材12的密度是較鄰接區域更高。但，不限於此，線狀壓榨部40亦可為其全區域被壓榨之溝狀壓榨部。又，吸收性芯材12的角部12A、一對前側狹縫52等之間，亦可非設置線狀壓榨部40，而是隔著較大間隔設置複數個點狀壓榨部。 [0076] 線狀壓榨部40與其鄰接區域之吸收性芯材12的基重之比較，可藉由習知的方法進行即可。例如，藉由電子顯微鏡，對將吸收性芯材12朝厚度方向切斷後之斷面進行攝像，以目視比較密度差，或計算纖維的數量進行比較等的方法。其他，亦可將對象部位作為樣品從衛生棉1切出，然後用面積除各樣品的質量，藉此算出基重(g／m
2)，再用厚度除該基重，算出密度(g／m
3)後再進行比較。再者，若比較樣品的條件相同的話，亦可在肌膚側薄片11及非肌膚側薄片13接著於吸收性芯材12的狀態下進行比較。 [0077] 又，在一對前側狹縫52各自的寬度方向之兩側，設置黏著區域21為佳。同樣地，在後側狹縫53的寬度方向之兩側，設置黏著區域21為佳。藉此，在以一對前側狹縫52所區劃的吸收性芯材12之3個區域12A，12B、及以後側狹縫53所區劃的吸收性芯材12之2個區域12A的基底部分，設置黏著區域21，再將該基底部分固定於內褲。並且，在較黏著區域21更靠近長度方向的外側，設有第1線狀壓榨部41~第3線狀壓榨部43。因此，以一對前側狹縫52、後側狹縫53等所區劃之吸收性芯材12的部位12A、12B，在往上提起內褲時不會傾倒、彎折，吸收性芯材12不會扭曲或彎折，容易穿戴衛生棉1。 [0078] 又，在本實施形態的衛生棉1，第1線狀壓榨部41的一部分及第2線狀壓榨部42的一部分設在較黏著區域21更靠近長度方向的外側。在此情況，在平面視角，第1線狀壓榨部41之其他一部分(圖5、圖6等之符號411，412)、及第2線狀壓榨部42之其他一部分(圖5、圖6中之符號421，422)與黏著區域21重複為佳。 [0079] 藉此，線狀壓榨部40(41，42)與黏著區域21重複，自固定於內褲之部位連續，使得吸收性芯材12的角部12A之剛性提高。因此，當往上提起內褲時，吸收性芯材12的角部12容易維持沿著內褲之狀態，變得不易傾倒且不易彎折。因此，使吸收性芯材12的角部12A不會扭曲或彎折，容易穿戴衛生棉1。 [0080] 且，如圖5所示，在長度方向的前側，在平面視角，第1線狀壓榨部41A的一端部411及另一端部412是與黏著區域21重複，第2線狀壓榨部42A的一端部421及另一端部422是與黏著區域21重複。亦即，前側之第1線狀壓榨部41A及前側之第2線狀壓榨部42A形成為從與黏著區域21重複的區域通過吸收性芯材12的角部12A再次返回至與黏著區域21重複的區域之形狀。 [0081] 因此，從固定於內褲的2個部位(圖5中的411與412、421與422等)連續而使吸收性芯材12的角部12A之剛性提高。因此，當往上提起內褲時，吸收性芯材12的角部12A變得更不會傾倒、彎折，使得吸收性芯材12的角部12A不會扭曲或彎折，容易穿戴衛生棉1。 [0082] 又，前側之第1線狀壓榨部41A及前側之第2線狀壓榨部42A係具有從長度方向的外側朝中央側折返之折返部44(例如圖5中的b~d的部分)。同樣地，後側之第1線狀壓榨部41B及後側之第2線狀壓榨部42B亦具有從長度方向的外側朝中央側折返之折返部44(例如圖6中的a~c的部分)。 [0083] 換言之，各線狀壓榨部40的從長度方向之最外側的端部到一端為止的部位(例如圖5中的c~a、圖6中的b~d)與從前述外側的端部至各線狀壓榨部40的另一端為止的部位(例如圖5中的c~e、圖6中的b~d)是在寬度方向上分離。 [0084] 因此，僅線狀壓榨部40(41，42)折返，即可在吸收性芯材12之角部12A，使吸收性芯材12被壓榨之區域變大，使得吸收性芯材12的角部12A之剛性進一步提高。又，折返部44係具有長度方向的成分與寬度方向的成分，因此，被折返部44所包圍的區域(以斜線所示的部分)容易維持平面形狀。因此，當往上提起內褲時，吸收性芯材12的角部12A變得更不會傾倒、彎折，使得吸收性芯材12的角部12A不會扭曲或彎折，容易穿戴衛生棉1。 [0085] 且，線狀壓榨部40(41、42)的折返部44係略呈心形，折返部44所包圍的區域成為略被封閉的區域。因此，使得衛生棉1的設計性提高，並且被折返部44所包圍的區域，其內側的吸收性芯材12之密度提高，因此，變得更容易維持平面形狀。 [0086] 又，在衛生棉1的前側區域R1(圖5)，設有一對前側狹縫52，其間的吸收性芯材12之部位12B形成略心形。因此，在長度方向上，前側之第1線狀壓榨部41A、與前側之第2線狀壓榨部42A、及第3線狀壓榨部43重複之吸收性芯材12的部位，其輪廓呈凹凸形狀，並具有預定數量(在此，4個)之突出部p1～p4。又，由於在長度方向上，前側之第1線狀壓榨部41A、與前側之第2線狀壓榨部42A、及第3線狀壓榨部43係沿著吸收性芯材12的輪廓，且折返部44大致呈心形，故，具有前述預定數量(4個)以上之突出部p1～p6(6個)。 [0087] 同樣地，在長度方向上，與後側之第1線狀壓榨部41B及後側之第2線狀壓榨部42B重複之吸收性芯材12的部位(圖6)，其輪廓呈凹凸形狀，並具有預定數量(在此，8個)之突出部p1～p8。又，由於後側之第1線狀壓榨部41B及後側之第2線狀壓榨部42B係沿著吸收性芯材12的輪廓，故，具有與前述預定數量(8個)相同數量之突出部p1～p8。 [0088] 衛生棉1之後側區域R3的輪廓呈凹凸形狀，且線狀壓榨部40(41、42)沿著該輪廓，藉此，當吸收性芯材12因應穿用者的動作變形時，能夠吸收性芯材12容易沿著突出部p1~p8之間的谷部p0進行彎折，使皺紋的產生變得一致。因此，可防止吸收性芯材12被折疊成皺巴巴，能夠減輕因無秩序的皺紋產生所引起之間隙的產生、穿戴衛生棉1時之不舒服感等。又，藉由在衛生棉1的後側區域R3設置複數個谷部p0，可因應穿用者的各種動作，使一定的彎折皺紋產生。 [0089] 如此，線狀壓榨部40係沿著吸收性芯材12的輪廓形成。具體而言，從吸收性芯材12的輪廓向內1mm~10mm左右的內側，以與吸收性芯材12的輪廓略相同形狀的方式形成線狀壓榨部40。藉此，可對使用者賦予藉由線狀壓榨部40的內側之膨脹所產生的穿戴性佳的印象、具有高級感的印象等。又，在本實施形態的衛生棉1，為了提升貼身性，在吸收性芯材12設置狹縫52、53，或輪廓呈凹凸形狀，及吸收性芯材12的形狀為其特徵。因此，藉由使線狀壓榨部40沿著吸收性芯材12的輪廓，能夠使使用者認識該特徵之吸收性芯材12的形狀。 [0090] 以上，說明了關於本創作的實施形態，但前述實施形態是用來容易理解本創作用之形態，並非用來限定解釋本創作者。又，本創作在不超出其技術思想範圍下，能夠加以變更、改良等，並且本創作當然亦包含其等價物。

However, the present invention is not limited thereto, and the present invention is also applicable to other absorbent articles such as a sheet for secretions, a urine absorption pad, and the like. [0031] ===Basic structure of the sanitary napkin 1 === Fig. 1 is a plan view of the sanitary napkin 1 (hereinafter referred to as sanitary napkin) viewed from the skin side. Fig. 2 is a plan view of the sanitary napkin 1 viewed from the non-skin side. Fig. 3A is a schematic cross-sectional view of the sanitary napkin 1 taken along line AA of Fig. 1. Fig. 3B is a schematic cross-sectional view for explaining the sanitary napkin 1 of the point press portion 6 and the linear press portion 40. [0032] The sanitary napkin 1 has a longitudinal direction, a width direction, and a thickness direction orthogonal to each other. In the longitudinal direction, the side that abuts the lower abdomen of the wearer is referred to as the front side, and the side that abuts the buttocks of the wearer is referred to as the rear side. In the thickness direction, the side that abuts the wearer is referred to as the skin side, and the opposite side is referred to as the non-skin side. As shown in FIG. 3A, in the sanitary napkin 1, a pair of side sheets 2, a top sheet 3, a second sheet 4, an absorbent body 10, and a back sheet 5 are sequentially laminated from the skin side in the thickness direction. Each of the members 2 to 5 and 10 is joined to a member adjacent to each other in the thickness direction by an adhesive (not shown). Further, the top sheet 3 and the second sheet 4 are liquid-permeable sheets, and examples thereof include hot air non-woven fabrics. The back sheet 5 is a liquid-impermeable sheet, and examples thereof include a resin film of polyethylene (PE). The top sheet 3 and the back sheet 5 have a larger planar size than the absorbent body 10 to cover the entire plane of the absorbent body 10. The sanitary napkin 1 has a tampon main body portion 20 provided with the absorbent body 10, and a pair of wing portions 30 extending from the central portion in the longitudinal direction of the tampon main body portion 20 in the width direction. The wing portion 30 is formed by the side sheet 2 and the back sheet 5 which are extended outward from both side portions in the width direction of the top sheet 3. Further, the sanitary napkin 1 may be in the form without the wings 30. [0035] In the sanitary napkin 1, a region closer to the front side than the wing portion 30 in the longitudinal direction is referred to as a front side region R1, and a region in which the wing portion 30 is provided is referred to as a central region R2, and the wing portion 30 is closer to the longitudinal direction. The area on the back side is referred to as the rear side area R3. The sanitary napkin 1 is individually packaged by making a three-folded portion of the front side region R1 front side folded portion Ff and the rear side region R3 rear side folded portion Fb. [0036] An adhesive region 21 coated with an adhesive or the like is provided on the non-skin side surface of the tampon main body portion 20 (the non-skin side surface of the back sheet 5). When the sanitary napkin 1 is used, the adhesive region 21 is adhered to the side of the skin such as underwear, whereby the sanitary napkin 1 is fixed to the undergarment or the like. In FIG. 2, three adhesive regions 21 having a rectangular shape having long sides along the longitudinal direction are arranged at intervals in the longitudinal direction, and the rows of the three adhesive regions 21 are arranged at intervals in the width direction. Eight columns, however, the shape and number of the adhesive regions 21 are not limited to this. [0037] Similarly, the non-skin side surface of each wing portion 30 (the non-skin side surface of the back sheet 5) is provided with an adhesive portion 31 for the wing portion. When the sanitary napkin 1 is used, the wing portion adhesive region 31 is adhered to the non-skin side surface of the undergarment or the like, whereby the sanitary napkin 1 is fixed to the undergarment or the like. In FIG. 2, the two wing portions having the rectangular shape having the long sides along the longitudinal direction are arranged in the width direction by the adhesive region 31. However, the shape and the number of the blade portion adhesive regions 31 are not limited thereto. [0038] The absorbent body 10 is a member that absorbs excrement and remains inside, as shown in FIG. 3A, and has an absorbent core material 12; a skin side sheet 11 located closer to the skin side than the absorbent core material 12; The absorbent core material 12 is closer to the non-skin side sheet 13 on the non-skin side. [0039] The absorbent core material 12 is a high-absorbent polymer (so-called SAP) to which a liquid-absorbent granular material or the like is added to a pulp fiber or a cellulose-based absorbent fiber of a liquid-absorbent fiber, and is formed into a predetermined one. Shaper. The skin side sheet 11 is a liquid permeable sheet, and examples thereof include a tissue paper. The non-skin side sheet 13 may be a liquid permeable sheet or a liquid impermeable sheet, and may be, for example, tissue paper. The absorptive core material 12, the skin side sheet 11 and the non-skin side sheet 13 are planar shapes having substantially the same shape, and are joined by an adhesive (not shown) so as to cover the absorbent core from the skin surface side and the non-skin side surface, respectively. Material 12. [0040] Although not shown, a plurality of absorber-like press portions 14 are uniformly provided in the absorber 10 over the entire area of the plane. As shown in FIG. 3B, the absorber body 10 is pressed in the thickness direction (embossing) and is recessed in the thickness direction, and the density of the absorbent core material 12 is higher than the adjacent region. By absorbing the spot press portion 14, the rigidity of the absorber 10 is increased, so that excrement or the like is easily diffused in the longitudinal direction. [0041] As shown in FIG. 1, a plurality of dot press portions 6 and a plurality of linear press portions 40 are provided on the skin side surface of the sanitary napkin 1. As shown in FIG. 3B, the top sheet 3, the second sheet 4, and the absorbent body 10 are pressed and recessed toward the skin side in the thickness direction, and the absorbent portion is absorbed in the adjacent region, in the point press portion 6 and the linear press portion 40. The density of the core material 12 becomes high. [0042] A plurality of linear press sections 40 are disposed along the contour of the absorbent core 12. The plurality of point press portions 6 are arranged in a zigzag manner between one of the both side portions in the width direction of the central portion R2 of the sanitary napkin 1 and the linear press portion 40 with a large interval therebetween. Settings. [0043] ===About the absorbent body 10 === Fig. 4 is a plan view for explaining the sanitary napkin 1 of the absorbent body 10. A folding inducing portion 15 along the longitudinal direction is provided at a central portion in the width direction of the absorber 10. As shown in FIG. 3B, the folding body 10 is pressed and recessed from the non-skin side in the thickness direction, and the density of the absorbent core material 12 is higher than the adjacent region. By the folding inducing portion 15, the absorbent body 10 is easily bent in the longitudinal direction so as to protrude toward the skin side, and it is easy to adhere to the excretory opening (vaginal opening) of the wearer. Therefore, it is preferable to provide the folding inducing portion 15 at least in the central portion R2 of the longitudinal direction of the sanitary napkin 1. Further, the folding inducing portion 15 is not limited to being formed by pressing. For example, it is also possible to reduce the basis weight of the absorbent core material 12 in the longitudinal direction, or to perform the process of bending the absorbent body 10 along the longitudinal direction, or along the length, in the manufacturing process. The hot melt adhesive is applied in the direction to form the fold inducing portion 15. Further, the absorbent core member 12 has a pair of front side cutout portions 50, a pair of rear side cutout portions 51, a pair of front side slits 52, a rear side slit 53, and a front side hollow portion 54. In the portions 50 to 54, the absorptive core material 12 does not exist, and the rigidity is lower than the area where the absorptive core material 12 exists. Further, in the above-mentioned portions 50 to 54, the skin side sheet 11 and the non-skin side sheet 13 may or may not be present. [0046] The pair of front side notch portions 50 and the pair of rear side notch portions 51 are respectively disposed on the outer side in the longitudinal direction of the wing portion 30 and at both end portions in the width direction of the absorbent core member 12, and the absorbent core member 12 parts to be cut. Specifically, the absorptive core material 12 is cut into a mountain shape that is convex toward the inner side in the width direction, but the shape of the notch is not limited thereto. Further, the pair of front side notch portions 50 (a pair of second low basis weight regions) are provided on the side of the front side region R1 close to the center region R2 (wing portion 30), and are overlapped with the individual packaging front side folding portion Ff in the longitudinal direction. . The pair of rear side notch portions 51 (a pair of second low basis weight regions) are provided on the side of the rear side region R3 close to the center region R2 (wing portion 30), and overlap the rear side folding portion Fb in the longitudinal direction. The pair of front side slits 52 are portions that are formed to be elongated from the distal end of the absorbent core member 12 and that cut the absorbent core member 12 symmetrically, and are symmetrically disposed with respect to the longitudinal center line CL. The longitudinal center line CL is a line along the longitudinal direction which tangles the sanitary napkin 1 in the width direction. Moreover, the front side slit 52 is inclined toward the inner side in the longitudinal direction, and is inclined toward the inner side in the width direction, and is provided on the front side closer to the longitudinal direction than the front side notch portion 50. The rear side slit 53 is a portion that cuts the absorbent core member 12 in the longitudinal direction from the center in the width direction of the rear end of the absorbent core member 12 toward the inside. The rear side slit 53 extends in the longitudinal direction to a position overlapping the rear side notch portion 51. The front side hollow portion 54 is a portion that is cut at a position overlapping the pair of front side cutout portions 50 in the longitudinal direction, and is cut at a center portion in the width direction of the absorbent core member 12 in the width direction. [0050] The sanitary napkin 1 having the absorbent core member 12 having the above-described structure is easily attached to the wearer. Therefore, the excretion is less likely to leak, and the uncomfortable feeling of wearing the sanitary napkin 1 can be alleviated, and the wearability is good. The following instructions are about this. [0051] The central region R2 of the sanitary napkin 1 is easily deformed into a W-shaped cross section. Specifically, the folding inducing portion 15 allows the central portion in the width direction to easily protrude toward the skin side, and is in close contact with the excretory opening of the wearer. Moreover, it is affected by the rubber (elastic band) of the leg hole of the underwear, and both sides in the width direction rise toward the skin side, and wrap the wearer's labia. In the central region R2 of the sanitary napkin 1, a point press portion 6 and a linear press portion 40 are provided. Therefore, the side portion in the width direction is high in rigidity, and there is no collapse due to the gripping force of the wearer's foot, and it can be raised toward the skin side. The front side region R1 and the rear side region R3 of the sanitary napkin 1 are easily raised with a pair of front side notch portions 50 and a pair of rear side notch portions 51 in the longitudinal direction as a starting point. Therefore, the sanitary napkin 1 is easily deformed into the shape of the buttocks from the lower abdomen of the wearer to the buttocks, and can be attached to the wearer. Further, the front side region R1 and the rear side region R3 of the sanitary napkin 1 are easily twisted toward the central region R2 by the pair of front side notch portions 50 and the pair of rear side notch portions 51 (for example, in the longitudinal center) The line CL is easy to swing for the shaft). Therefore, the sanitary napkin 1 can follow various actions of the wearer and maintain the state of being in close contact with the wearer. Further, in the longitudinal direction, the pair of front side cutout portions 50 overlap the front side hollow portion 54 and the front side folding portion Ff. Further, in the longitudinal direction, the pair of rear side cutout portions 51 and the rear side folding portion Fb are repeated. Therefore, the front side region R1 and the rear side region R3 of the sanitary napkin 1 are easily erected to the central region R2 and are easily twisted. Further, in the pair of front side notch portions 50 and the pair of rear side notch portions 51, the sanitary napkin 1 has low rigidity and is easily deformed. Therefore, the side portion of the sanitary napkin 1 in the width direction of the central portion R2 is erected by the pair of front side notch portions 50 and the pair of rear side notch portions 51. Similarly, the rear side slit 53 and the front side hollow portion 54 are overlapped with the fold inducing portion 15 in the width direction. Therefore, the sanitary napkin 1 is erected in the central portion in the width direction of the central region R2, and is blocked by the rear slit 53 and the front hollow portion 54. That is, the W-shaped deformation of the sanitary napkin 1 in the central region R2 is not easily transmitted to the front side region R1 and the rear side region R3, and the front side region R1 and the rear side region R3 are deformed to follow the wearer's lower abdomen, buttocks, and the like. The curved face shape is close to the wearer. Further, the front side region R1 of the sanitary napkin 1 is easily bent by a pair of front side slits 52 to be wrapped around the lower abdomen of the wearer (the portion of the inverted triangle surrounded by the so-called bikini line). Further, when the wearer's feet are closed, the portion of the inverted triangle is reduced, and the remaining portion of the absorbent core member 12 can be avoided toward the front slit 52, and the absorbent core member 12 can be prevented from being folded into wrinkles. That is, in the front side slit 52, the top sheet 3 and the back sheet 5 are folded and folded, and the front side region R1 is attached to the lower abdomen of the wearer without a gap. [0057] Similarly, the rear side region R3 of the sanitary napkin 1 is easily bent along the wearer's buttocks by the rear side slit 53 to fit close to the wearer's buttocks. Further, the absorbent core members 12 on both sides of the rear side slits 53 are independent and easy to operate. Therefore, even when the wearer walks or the like, the movement of the right and left buttocks is different, the absorbent core member 12 can follow the left buttocks and the right buttocks, respectively, and can easily maintain the state of being in close contact with the buttocks. [0058] Thus, in the front side region R1 and the rear side region R3 of the sanitary napkin 1, such as the rear side slit 53, a slit along the longitudinal center line CL, or a pair of front side slits 52, from the longitudinal center line, is provided. It is preferable that the dots on the CL are radially provided with a plurality of slits. Thereby, the front side region R1 and the rear side region R3 of the sanitary napkin 1 easily become along the lower abdomen, buttocks, and the like of the wearer. Further, in the present embodiment, the pair of front side notch portions 50, the pair of rear side notch portions 51, the pair of front side slits 52, the rear side slits 53, and the front side hollow portion 54 are made of an absorbent core material. The basis weight of 12 is set to zero. However, the present invention is not limited thereto, and the absorbent core member 12 may be present in the above-mentioned portions 50 to 54, and the basis weight (mass per unit area [g/m2]) of the absorbent core member 12 is lower than that in the adjacent region. Just fine. In this case, in the above-described portions 50 to 54, the rigidity becomes lower than in other regions, and the same effect can be obtained. Further, the absorbent core member 12 may not have the above-described portions 50 to 54. Further, the comparison of the basis weights of the absorbent core members 12 between the portions 50 to 54 and the adjacent regions thereof may be carried out by a conventional method. For example, the target portion is cut out from the sanitary napkin 1 as a sample, and the mass and area of each sample are measured. Then, a method of comparing the mass per unit area is calculated. Further, when the conditions of the comparative sample are the same, the basis weights of the skin side sheet 11 and the non-skin side sheet 13 in the state of the absorbent core member 12 can be compared. === Regarding the linear press portion 40 === Fig. 5 is a view for explaining the linear press portion 40 provided in the front side region R1. Fig. 6 is a view for explaining the linear press portion 40 provided in the rear side region R3. As described above, a plurality of linear press portions 40 are provided along the contour of the absorbent core member 12 on the skin side surface of the sanitary napkin 1, and an adhesive region 21 is provided on the non-skin side surface of the sanitary napkin 1. From Fig. 4 to Fig. 6, the linear press portion 40 and the adhesive region 21 are depicted in a repeated manner in a plan view angle (viewed in the thickness direction). In the sanitary napkin 1 of the present embodiment, as shown in FIG. 4, the end portions 12a, 12b of the absorbent core member 12 in the longitudinal direction are located closer to the end portions 21a, 21b in the longitudinal direction of the adhesive region 21. The outside of the length direction. Therefore, both end portions of the absorbent core member 12 in the longitudinal direction are not overlapped with the adhesive region 21, and are not fixed to the undergarment. Therefore, the linear press portion 40 is provided at the corner portion 12A (the portion where the outline is indicated by a thick line) which is not fixed to the absorbent core member 12 of the undergarment. Specifically, in the longitudinal direction, the end portions 21a and 21b of the adhesive region are further outward and both end portions in the width direction (that is, the pair of longitudinal center lines CL are one side and the other side in the width direction). The "first linear press portion 41 (first recess)" and the "second linear press portion 42 (second recess)" are provided. Further, the first linear press portion 41 and the second linear press portion 42 are provided on both sides in the longitudinal direction. Further, the first linear press portion 41A on the front side in the longitudinal direction and the second linear press portion 41B on the front side are symmetrical to the longitudinal center line CL, and the first linear press portion 41B on the rear side. The second linear press portion 42B on the rear side has a shape that is symmetrical with respect to the longitudinal center line CL, but is not limited thereto. Further, the first linear press portion 41A and the second linear press portion 42A on the front side, the first linear press portion 41B on the rear side, and the second linear press portion 42B on the rear side have different shapes. Not limited to this. As shown in FIG. 3B, the linear press portion 40 is recessed in the thickness direction, and the density of the absorbent core member 12 is higher than the adjacent region where the absorbent core member 12 is not pressed. Therefore, the rigidity is high in the portion where the linear press portion 40 is provided. Therefore, the corner portion 12A of the absorbent core member 12 is also increased in rigidity by the first linear press portion 41 and the second linear press portion 42, and the surface shape can be easily maintained. Therefore, when the undergarment to which the sanitary napkin 1 is attached is lifted up for wearing the sanitary napkin 1, even if the corner portion 12A of the absorbent core member 12 is not fixed to the undergarment, it is difficult to be tilted or bent toward the wearer side. Therefore, when the undergarment is intimately attached to the wearer via the sanitary napkin 1, the corner portion 12A of the absorbent core member 12 is not twisted or bent, and the sanitary napkin 1 can be easily worn appropriately. [0066] In other words, according to the sanitary napkin 1 of the present embodiment in which the linear press portion 40 is provided at the corner portion 12A of the absorbent core member 12, the sanitary napkin 1 can be appropriately worn even if the length of the adhesive region 21 is short. . Therefore, the amount of application of the adhesive forming the adhesive region 21 can be reduced, and when the individual packaging is performed, the release paper covering the adhesive region 21 can be reduced, so that the cost can be reduced. Further, the first linear press portion 41 and the second linear press portion 42 are separated in the width direction and are discontinuous. Therefore, the front side region R1 and the rear side region R3 of the sanitary napkin 1 are not easily fixed in a planar shape, and are compliantly operated, and both end portions in the width direction are easily operated independently. Therefore, the front side region R1, the rear side region R3, and the like of the sanitary napkin 1 are easily bent along the wearer's lower abdomen, buttocks, and the like. Moreover, the left hip and the right hip can be respectively followed, and the state of being in close contact with the buttocks can be maintained. As described above, the sanitary napkin 1 of the present embodiment can be suitably worn, and the fit is also good. Further, the first linear press portion 41 and the second linear press portion 42 are provided on the outer side of the end portions 21a and 21b of the adhesive region 21 in the longitudinal direction and in the adhesive region 21 in the width direction. The ends 21a, 21b are further outside. Thereby, the linear press portion 40 can be provided at the corner portion 12A of the absorbent core member 12 which is easily poured and bent when the undergarment is lifted up. Therefore, the corner portion 12A of the absorbent core member 12 can be more reliably prevented from being twisted or bent, and the sanitary napkin 1 can be easily worn. Further, the first linear press portion 41 and the second linear press portion 42 may be provided on at least one side in the longitudinal direction. However, the first linear press portion 41 and the first linear press portion 41 are provided on both sides in the longitudinal direction. The second linear press portion 42. Thereby, the four corner portions 12A of the absorbent core member 12 can be prevented from being twisted or bent, and the sanitary napkin 1 can be easily worn. [0070] In this case, when the first linear press portion 41A and the second linear press portion 42A on the front side and the first linear press portion 41B and the second linear press portion 42B on the rear side are continuous, there may be The sanitary napkin 1 is conveyed to the side of the front side region R1 and the rear side region R3 in the side portion of the central portion R2 in the width direction. Therefore, the first linear press portion 41A on the front side and the first linear press portion 41B on the rear side are separated in the longitudinal direction, and the second linear press portion 42A on the front side and the second linear press portion 42B on the rear side are placed. Separation in the length direction is preferred. Thereby, the front side region R1 and the rear side region R3 of the sanitary napkin 1 are easily attached to the wearer's lower abdomen, buttocks, and the like, and the fit is good. Further, between the first linear press portion 41A on the front side and the second linear press portion 42A on the front side, a pair of front slits 52 are provided, and the first linear press portion 41B and the rear side on the rear side are provided. A rear slit 53 is provided between the second linear press portions 42B. As described above, when the front side slit 52 and the rear side slit 53 (low basis weight area) are provided in the absorbent core member 12, the fit of the sanitary napkin 1 can be improved. Further, when the undergarment is lifted up, the portion on the outer side in the width direction is more likely to be poured or bent than the front side slit 52, the rear side slit 53, and the like. Therefore, the sanitary napkin 1 of the present embodiment is provided with a first linear shape at a portion on the outer side in the width direction of the front slit 52, the rear slit 53, and the like, that is, at the corner portion 12A of the absorbent core member 12. The press portion 41, the second linear press portion 42, and the like are more effective. Further, not only the corner portion 12A of the absorbent core member 12 but also the portion 12B of the absorbent core member 12 between the pair of front side slits 52 may be poured or bent when the sanitary napkin 1 is worn. Therefore, the end portion 21a of the adhesive region is further forward (outer) in the longitudinal direction, and a linear press portion 40 (hereinafter also referred to as a third linear press portion 43) is provided between the pair of front slits 52 (the first 3 recesses)) is better. Thereby, the rigidity of the portion 12B of the absorbent core member 12 between the pair of front side slits 52 is improved, and the surface shape is easily maintained. Therefore, the portion 12B of the absorbent core member 12 between the pair of front side slits 52 is not twisted or bent, and the sanitary napkin 1 can be easily worn. Further, the third linear press portion 43 is separated from the first linear press portion 41 in the width direction, and is preferably separated from the second linear press portion 42 in the width direction. Thereby, the three fields 12A, 12B of the absorbent core material 12 partitioned by the pair of front side slits 52 can be easily and independently operated, and the front side region R1 of the sanitary napkin 1 is easily bent along the lower abdomen of the wearer. Further, the linear press portion 40 (the first recessed portion, the second recessed portion, and the third recessed portion) may be at least one portion of the absorbent core member 12 being pressed, and is not limited to the top surface as shown in the present embodiment. The sheet 3 is pressed. Further, in the linear press portion 40 of the present embodiment, a plurality of dot press portions are arranged in a line at a narrow interval, and the average density of the absorbent core member 12 of the linear press portion 40 is higher than that of the adjacent region. However, the present invention is not limited thereto, and the linear press portion 40 may be a groove-shaped press portion in which the entire region is pressed. Further, between the corner portion 12A of the absorbent core member 12, the pair of front slits 52, and the like, a plurality of dot press portions may be provided without being provided with the linear press portion 40 at a large interval. [0076] The comparison of the basis weight of the linear press portion 40 and the absorbent core member 12 in the adjacent region thereof can be carried out by a conventional method. For example, a section in which the absorptive core material 12 is cut in the thickness direction is imaged by an electron microscope, and the difference in density is compared visually, or the number of fibers is calculated and compared. Alternatively, the target portion may be cut out from the sanitary napkin 1 as a sample, and then the mass of each sample may be divided by area to calculate the basis weight (g/m). 2 ), and then divide the basis weight by the thickness to calculate the density (g/m) 3 ) then compare. Further, when the conditions of the comparative sample are the same, the skin side sheet 11 and the non-skin side sheet 13 can be compared with each other in the state of the absorbent core member 12. Further, it is preferable to provide the adhesive region 21 on both sides in the width direction of each of the pair of front slits 52. Similarly, it is preferable to provide the adhesive region 21 on both sides in the width direction of the rear side slit 53. Thereby, the base portions of the two regions 12A of the absorbent core member 12 partitioned by the three regions 12A, 12B of the absorbent core member 12 and the rear slit 53 are defined by the pair of front slits 52, An adhesive area 21 is provided, and the base portion is fixed to the undergarment. Further, the first linear press portion 41 to the third linear press portion 43 are provided on the outer side in the longitudinal direction of the adhesive region 21. Therefore, the portions 12A and 12B of the absorbent core member 12 which are partitioned by the pair of the front side slits 52 and the rear side slits 53 are not tilted or bent when the underwear is lifted upward, and the absorbent core member 12 does not. Twisted or bent, easy to wear sanitary napkins 1. Further, in the sanitary napkin 1 of the present embodiment, a part of the first linear press portion 41 and a part of the second linear press portion 42 are provided on the outer side in the longitudinal direction of the adhesive region 21. In this case, the other portion of the first linear press portion 41 (symbols 411 and 412 in FIGS. 5 and 6) and the other portion of the second linear press portion 42 in the plane view (FIG. 5 and FIG. 6) The symbol 421, 422) is preferably repeated with the adhesive region 21. Thereby, the linear press portion 40 (41, 42) overlaps with the adhesive region 21, and is continuous from the portion fixed to the undergarment, so that the rigidity of the corner portion 12A of the absorbent core member 12 is improved. Therefore, when the underpants are lifted up, the corner portion 12 of the absorbent core member 12 is easily maintained in the state of the underpants, and it becomes difficult to fall over and is not easily bent. Therefore, the corner portion 12A of the absorbent core member 12 is not twisted or bent, and the sanitary napkin 1 is easily worn. As shown in FIG. 5, in the front side in the longitudinal direction, the one end portion 411 and the other end portion 412 of the first linear press portion 41A are overlapped with the adhesive region 21 at the plane viewing angle, and the second linear press portion is formed. One end portion 421 and the other end portion 422 of 42A are overlapped with the adhesive region 21. In other words, the first linear press portion 41A on the front side and the second linear press portion 42A on the front side are formed to return again from the corner portion 12A of the absorbent core member 12 to the overlap with the adhesive region 21 from the region overlapping the adhesive region 21. The shape of the area. Therefore, the rigidity of the corner portion 12A of the absorbent core member 12 is increased from the two portions (411, 412, 421, and 422 in FIG. 5) fixed to the undergarment. Therefore, when the undergarment is lifted up, the corner portion 12A of the absorbent core member 12 becomes less likely to be poured and bent, so that the corner portion 12A of the absorbent core member 12 is not twisted or bent, and the sanitary napkin 1 is easily worn. . Further, the first linear press portion 41A on the front side and the second linear press portion 42A on the front side have a folded portion 44 that is folded back toward the center side from the outer side in the longitudinal direction (for example, the portion b to d in FIG. 5) ). Similarly, the first linear press portion 41B on the rear side and the second linear press portion 42B on the rear side also have a folded portion 44 that is folded back toward the center side from the outer side in the longitudinal direction (for example, a part of a to c in Fig. 6). ). In other words, a portion from the outermost end portion in the longitudinal direction to one end of each of the linear press portions 40 (for example, c to a in FIG. 5 and b to d in FIG. 6) and an end portion from the outer side. The portions up to the other end of each of the linear press portions 40 (for example, c to e in Fig. 5 and b to d in Fig. 6) are separated in the width direction. Therefore, only the linear press portion 40 (41, 42) is folded back, that is, the region where the absorbent core material 12 is pressed is enlarged at the corner portion 12A of the absorbent core member 12, so that the absorbent core member 12 is made larger. The rigidity of the corner portion 12A is further improved. Further, since the folded portion 44 has components in the longitudinal direction and components in the width direction, the region surrounded by the folded portion 44 (portion indicated by oblique lines) easily maintains the planar shape. Therefore, when the undergarment is lifted up, the corner portion 12A of the absorbent core member 12 becomes less likely to be poured and bent, so that the corner portion 12A of the absorbent core member 12 is not twisted or bent, and the sanitary napkin 1 is easily worn. . Further, the folded portion 44 of the linear press portion 40 (41, 42) is slightly in a heart shape, and the region surrounded by the folded portion 44 is a slightly closed region. Therefore, the design of the sanitary napkin 1 is improved, and the density of the absorbent core member 12 on the inner side of the region surrounded by the folded portion 44 is improved, so that it is easier to maintain the planar shape. Further, in the front side region R1 (FIG. 5) of the sanitary napkin 1, a pair of front side slits 52 are provided, and the portion 12B of the absorbent core member 12 therebetween is formed in a substantially heart shape. Therefore, in the longitudinal direction, the portion of the first linear press portion 41A on the front side, the second linear press portion 42A on the front side, and the third linear press portion 43 overlap the core member 12, and the outline thereof is uneven. The shape has a predetermined number (here, four) of protrusions p1 to p4. Further, in the longitudinal direction, the first linear press portion 41A on the front side, the second linear press portion 42A on the front side, and the third linear press portion 43 are along the contour of the absorbent core member 12, and are folded back. Since the portion 44 is substantially in the shape of a heart, it has the predetermined number (four or more) of the projections p1 to p6 (six). Similarly, in the longitudinal direction, the portion of the absorbent core member 12 (FIG. 6) that overlaps the first linear press portion 41B on the rear side and the second linear press portion 42B on the rear side has a contour The concavo-convex shape has a predetermined number (here, eight) of protrusions p1 to p8. Further, since the first linear press portion 41B on the rear side and the second linear press portion 42B on the rear side are along the contour of the absorbent core member 12, they have the same number of protrusions as the predetermined number (eight). Parts p1 to p8. [0088] The contour of the rear side region R3 of the sanitary napkin 1 has an uneven shape, and the linear press portion 40 (41, 42) is along the contour, whereby when the absorbent core member 12 is deformed in response to the action of the wearer, The absorbable core material 12 is easily bent along the valley portion p0 between the protruding portions p1 to p8 to make the generation of wrinkles uniform. Therefore, it is possible to prevent the absorbent core material 12 from being folded into wrinkles, and it is possible to reduce the occurrence of a gap caused by disordered wrinkles, an uncomfortable feeling when the sanitary napkin 1 is worn, and the like. Further, by providing a plurality of valley portions p0 in the rear side region R3 of the sanitary napkin 1, it is possible to generate a certain amount of wrinkles in response to various actions of the wearer. [0089] As such, the linear press portion 40 is formed along the contour of the absorbent core 12. Specifically, the linear press portion 40 is formed from the inner side of the outline of the absorbent core member 12 in the inner side of about 1 mm to 10 mm so as to have a shape slightly the same as that of the absorbent core member 12. Thereby, the user can be given an impression of good wearability by the expansion of the inner side of the linear press section 40, an impression of high-grade feeling, and the like. Further, in the sanitary napkin 1 of the present embodiment, in order to improve the fit, the slits 52 and 53 are provided in the absorbent core member 12, or the outline has a concavo-convex shape, and the shape of the absorbent core member 12 is characterized. Therefore, by making the linear press portion 40 along the contour of the absorbent core member 12, the user can recognize the shape of the absorbent core member 12 of the feature. [0090] Although the embodiment of the present invention has been described above, the above embodiment is for easily understanding the form of the present creation, and is not intended to limit the explanation to the creator. Moreover, this creation can be changed, improved, etc. without exceeding the scope of its technical ideas, and the creation of course also includes its equivalent.
