Description

接合構造體的製造方法及接合構造體
本發明是有關於一種接合構造體的製造方法及接合構造體。
先前，已知有將由不同材料所構成的第一構件及第二構件接合的接合方法（例如，參照專利文獻1）。
在專利文獻1中，揭示有藉由半導體雷射將作為樹脂材料的第一構件與作為金屬材料的第二構件接合的接合方法。第二構件的邊界面被砂紙等磨損成凹凸狀。此外，藉由對第一構件及第二構件的邊界面照射半導體雷射，而在第二構件的邊界面半導體雷射被吸收。藉此，將邊界面附近的第一構件熔融，該第一構件陷入凹凸中而被固化。其結果，將第一構件及第二構件接合。
[現有技術文獻] [專利文獻] [專利文獻1]日本專利特開2008-162288號公報
[發明所欲解決之課題]
然而，在所述的現有的接合方法中，由於對第二構件的邊界面照射的半導體雷射容易被反射，因此難以將雷射的能量有效率地轉換為熱。因此，在現有的接合方法中，必須將雷射設為高能量，故而存在樹脂材料容易熱劣化（例如，燒焦、變色、變形等）的問題點。
本發明是為了解決所述課題而完成者，本發明的目的在於提供一種可抑制第二構件熱劣化的接合構造體的製造方法及接合構造體。 [解決課題之手段]
本發明的接合構造體的製造方法是接合有第一構件與第二構件的接合構造體的製造方法，其包括：在第一構件的表面形成具有開口的穿孔部，並且在穿孔部的內周面形成向內側突出的突出部的步驟；將第一構件的形成有穿孔部的區域與第二構件鄰接配置的步驟；及藉由自第二構件側向第一構件的形成有穿孔部的區域照射雷射，而在第一構件的穿孔部中填充第二構件並使其固化的步驟。
藉由以所述方式構成，由於容易藉由突出部將所照射的接合用的雷射封閉於穿孔部的內部，因此可將接合用的雷射的能量有效率地轉換為熱。藉此，可將接合用的雷射的能量抑制為所需最低限度，因此可抑制第二構件熱劣化。
在所述接合構造體的製造方法中，穿孔部可以在深度方向上開口徑自表面側朝向底部變大的第一擴徑部，與在深度方向上開口徑自表面側朝向底部變小的第一縮徑部相連的方式而形成，且將突出部配置於表面側。
在所述接合構造體的製造方法中，穿孔部可以在深度方向上開口徑自表面側朝向底部變小的第二縮徑部、在深度方向上開口徑自表面側朝向底部變大的第二擴徑部、及在深度方向上開口徑自表面側朝向底部變小的第三縮徑部相連的方式而形成，且將突出部配置於進入底部側的位置。
在所述接合構造體的製造方法中，第一構件可為金屬、熱塑性樹脂、或熱固性樹脂。
在所述接合構造體的製造方法中，第二構件可為使雷射透過的樹脂。
本發明的接合構造體是藉由所述的任一種接合構造體的製造方法所製造。
藉由以所述方式構成，由於容易藉由突出部將所照射的接合用的雷射封閉於穿孔部的內部，因此可將接合用的雷射的能量有效率地轉換為熱。藉此，可將接合用的雷射的能量抑制為所需最低限度，因此可抑制第二構件熱劣化。 [發明的效果]
根據本發明的接合構造體的製造方法及接合構造體，可抑制第二構件熱劣化。
以下，參照圖式對本發明的實施方式進行說明。 （第一實施方式）
首先，參照圖1對本發明的第一實施方式的接合構造體100進行說明。
接合構造體100如圖1所示，是接合有由不同材料所構成的第一構件10及第二構件20者。在第一構件10的表面13形成有具有開口的穿孔部11，且在該穿孔部11的內周面形成有向內側突出的突出部12。此外，在第一構件10的穿孔部11中填充並固化有第二構件20。再者，圖1是將第一構件10及第二構件20的接合界面放大進行示意性表示的圖，實際上設置有多個穿孔部11，但在圖1中僅示出一個。
第一構件10的材料為金屬、熱塑性樹脂、或熱固性樹脂。第二構件20的材料是使雷射透過的樹脂，為熱塑性樹脂、或熱固性樹脂。該第二構件20的關於在下文所述的接合時所照射的雷射較佳為在厚度為3 mm時，透過率為15%以上。
作為所述金屬的一例，可列舉：鐵系金屬、不鏽鋼系金屬、銅系金屬、鋁系金屬、鎂系金屬、及該些金屬的合金。另外，可為金屬成型體，亦可為鋅壓鑄、鋁壓鑄、粉末冶金等。
作為所述熱塑性樹脂的一例，可列舉：聚氯乙烯（Polyvinyl chloride，PVC）、聚苯乙烯（Polystyrene，PS）、丙烯腈-苯乙烯（Acrylonitrile-styrene，AS）、丙烯腈-丁二烯-苯乙烯（Acrylonitrile-butadiene-styrene，ABS）、聚甲基丙烯酸甲酯（Polymethyl methacrylate，PMMA）、聚乙烯（Polyethylene，PE）、聚丙烯（Polypropylene，PP）、聚碳酸酯（Polycarbonate，PC）、改質聚苯醚（modified-Polyphenyleneether，m-PPE）、聚醯胺6（Polyamide 6，PA6）、聚醯胺66（PA66）、聚縮醛（Polyacetal，POM）、聚對苯二甲酸乙二酯（Polyethylene terephthalate，PET）、聚對苯二甲酸丁二酯（Polybutylene terephthalate，PBT）、聚碸（Polysulfone，PSF）、聚芳酯（Polyarylate，PAR）、聚醚醯亞胺（Polyetherimide，PEI）、聚苯硫醚（Polyphenylenesulfide，PPS）、聚醚碸（Polyether sulfone，PES）、聚醚醚酮（Polyetheretherketone，PEEK）、聚醯胺醯亞胺（Polyamideimide，PAI）、液晶聚合物（Liquid crystal polymer，LCP）、聚偏二氯乙烯（Polyvinylidene chloride，PVDC）、聚四氟乙烯（Polytetrafluoroethylene，PTFE）、聚氯三氟乙烯（Polychlorotrifluoroethylene，PCTFE）、及聚偏二氟乙烯（Polyvinylidene Fluoride，PVDF）。另外，亦可為熱塑性彈性體（Thermoplastic elastomer，TPE），作為TPE的一例，可列舉熱塑性烯烴（Thermoplastic olefin，TPO）（烯烴系）、熱塑性苯乙烯（Thermoplastic styrene，TPS）（苯乙烯系）、熱塑性酯（Thermoplastic polyester elastomer，TPEE）（酯系）、熱塑性胺基甲酸酯（Thermoplastic urethane，TPU）（胺基甲酸酯系）、熱塑性尼龍（Thermoplastic polyamide，TPA）（尼龍系）、及熱塑性氯乙烯（Polyvinyl chloride based thermoplastic，TPVC）（氯乙烯系）。
作為所述熱固性樹脂的一例，可列舉：環氧（Epoxy，EP）樹脂、聚胺基甲酸酯（Polyurethane，PUR）樹脂、脲甲醛（Urea-formaldehyde，UF）樹脂、三聚氰胺甲醛（Melamine formaldehyde，MF）樹脂、酚甲醛（Phenol formaldehyde，PF）樹脂、不飽和聚酯（Unsaturated polyester，UP）樹脂、及矽（Silicone，SI）樹脂。另外，亦可為纖維強化塑膠（Fiber reinforced plastics，FRP）。
再者，亦可在所述的熱塑性樹脂及熱固性樹脂中添加填充劑。作為填充劑的一例，可列舉無機系填充劑（玻璃纖維、無機鹽類等）、金屬系填充劑、有機系填充劑、及碳纖維等。
穿孔部11在俯視下為大致圓形的非貫通孔，在第一構件10的表面13形成有多個。穿孔部11的表面13的開口徑R1較佳為30 μm以上、100 μm以下。其原因在於：若開口徑R1小於30 μm，則無法將所照射的接合用的雷射充分封閉於穿孔部11內，存在將接合用的雷射的能量轉換為熱的轉換效率降低的情形。另一方面，原因在於：若開口徑R1大於100 μm，則每單位面積的穿孔部11的個數減少，存在將接合用的雷射的能量轉換為熱的轉換效率降低的情形。另外，穿孔部11的深度較佳為10 μm以上。其原因在於：若深度小於10 μm，則存在將接合用的雷射的能量轉換為熱的轉換效率降低的情形。
另外，穿孔部11的間隔（既定的穿孔部11的中心與鄰接於既定的穿孔部11的穿孔部11的中心的距離）較佳為200 μm以下。其原因在於：若穿孔部11的間隔大於200 μm，則每單位面積的穿孔部11的個數減少，存在將接合用的雷射的能量轉換為熱的轉換效率降低的情形。再者，作為穿孔部11的間隔的下限的一例，為穿孔部11重疊而不崩壞的距離。另外，較佳為穿孔部11的間隔相同。其原因在於：若穿孔部11的間隔相等，則照射接合用的雷射時的熱的分佈變得等向。
此處，第一實施方式的穿孔部11是以在深度方向（Z方向）上開口徑自表面13側朝向底部113變大的擴徑部111與在深度方向上開口徑自表面13側朝向底部113變小的縮徑部112相連的方式而形成。擴徑部111是以曲線狀擴徑的方式而形成，縮徑部112是以曲線狀縮徑的方式而形成。再者，擴徑部111為本發明的「第一擴徑部」的一例，縮徑部112為本發明的「第一縮徑部」的一例。
此外，擴徑部111是配置於表面13側，並且縮徑部112是配置於底部113側。因此，在穿孔部11中，擴徑部111與縮徑部112的邊界部分的開口徑（內徑）R2變得最大，且開口徑R1變得小於開口徑R2。藉此，突出部12是配置於第一構件10的表面13側。該突出部12例如是跨周方向上的全長而形成，且形成為環狀。
該穿孔部11例如是藉由照射加工用的雷射而形成。作為雷射的種類，就可進行脈衝振盪的觀點而言，可選擇光纖雷射（fiber laser）、釔鋁石榴石（yttrium aluminum garnet，YAG）雷射、釩酸釔（yttrium orthovanadate，YVO4 ）雷射、半導體雷射、二氧化碳雷射、準分子雷射（excimer laser），若考慮雷射的波長，則較佳為光纖雷射、YAG雷射、YAG雷射的二次諧波、YVO4 雷射、半導體雷射。再者，雷射的輸出是考慮雷射的照射直徑、第一構件10的材料的種類、第一構件10的形狀（例如厚度）等而設定。例如，雷射的輸出上限較佳為40 W。其原因在於：若雷射的輸出超過40 W，則能量變大，難以形成具有突出部12的穿孔部11。
作為形成穿孔部11的裝置的一例，可列舉歐姆龍（OMRON）製造的光纖雷射雕刻機（fiber laser marker）MX-Z2000或MX-Z2050。關於該光纖雷射雕刻機，可照射一個脈衝由多個次脈衝所構成的雷射。因此，容易使雷射的能量集中於深度方向，故而適宜於形成穿孔部11。具體而言，若對第一構件10照射雷射，則藉由將第一構件10局部熔融而進行穿孔部11的形成。此時，由於雷射由多個次脈衝所構成，因此經熔融的第一構件10不易飛散，而容易堆積於穿孔部11的附近。此外，若進行穿孔部11的形成，則藉由將經熔融的第一構件10堆積於穿孔部11的內部而形成突出部12。再者，雷射的照射方向例如是垂直於表面13的方向，穿孔部11的軸心相對於表面13而垂直。
再者，作為利用所述光纖雷射雕刻機的加工條件，較佳為次脈衝的一個週期為15 ns以下。其原因在於：若次脈衝的一個週期超過15 ns，則因導熱導致能量變得容易擴散，而變得難以形成具有突出部12的穿孔部11。再者，次脈衝的一個週期是照射一次次脈衝的時間與該次脈衝的照射結束起至開始下一次次脈衝的照射為止的間隔的合計時間。
另外，作為利用所述光纖雷射雕刻機的加工條件，較佳為一個脈衝的次脈衝數為2個以上且為50個以下。其原因在於：若次脈衝數超過50個，則次脈衝每單位的輸出變小，而變得難以形成具有突出部12的穿孔部11。
此外，第二構件20是接合於形成有穿孔部11的第一構件10的表面13。該第二構件20例如藉由雷射熔著而接合於第一構件10。藉此，在將第二構件20填充於穿孔部11中的狀態下進行固化。再者，作為接合用的雷射的種類，可選擇光纖雷射、YAG雷射、YVO4 雷射、半導體雷射、二氧化碳雷射、準分子雷射。
此種接合構造體100例如可應用於將樹脂外殼（省略圖示）接合於光電感應器的金屬件（省略圖示）的情形。於該情形時，金屬件相當於第一構件10，樹脂外殼相當於第二構件20。 -接合構造體的製造方法-
繼而，參照圖1～圖3，對第一實施方式的接合構造體100的製造方法進行說明。
首先，在第一構件10的表面13形成穿孔部11，並且在該穿孔部11的內周面形成突出部12。該穿孔部11及突出部12例如是如圖2所示，藉由照射一個脈衝由多個次脈衝所構成的雷射而形成。作為具體例，使用所述的光纖雷射雕刻機MX-Z2000或MX-Z2050而形成。
其後，如圖3所示，在第一構件10的表面13鄰接配置第二構件20。然後，在對第一構件10及第二構件20進行加壓的狀態下，自第二構件20側向第一構件10的表面13照射接合用的雷射。因此，該雷射的能量在第一構件10的表面13被轉換為熱，第一構件10的表面13的溫度變高。藉此，將第一構件10的表面13附近的第二構件20熔融，而將該第二構件20填充於穿孔部11中。其後，藉由將第二構件20固化，將第二構件20接合於第一構件10，而形成接合構造體100（參照圖1）。
此處，在第一實施方式中，藉由在穿孔部11的內周面形成有向內側突出的突出部12，而容易藉由突出部12將所照射的接合用的雷射封閉於穿孔部11的內部，因此可將接合用的雷射的能量有效率地轉換為熱。藉此，由於可將接合用的雷射的能量抑制為所需最低限度，因此可抑制第二構件20熱劣化。
再者，亦可在將第一構件10及第二構件20鄰接配置時，在第一構件10的表面13或第二構件20的表面設置雷射吸收層（省略圖示）。作為該雷射吸收層，可適當選擇對接合用的雷射的波長具有吸收性的顏料系或染料系的雷射吸收材等而使用。若以此種方式構成，則可實現將接合用的雷射的能量轉換為熱的轉換效率的提高。再者，雷射吸收層的厚度為了確保第二構件20向穿孔部11中的填充性，較佳為10 μm以下。另外，在滿足對第二構件20所要求的雷射的透過性的範圍內，亦可在第二構件20中調配雷射吸收材。 （第二實施方式）
繼而，參照圖4，對本發明的第二實施方式的接合構造體200進行說明。
接合構造體200如圖4所示，是接合有由不同材料所構成的第一構件30及第二構件20者。在第一構件30的表面33形成有具有開口的穿孔部31，且在該穿孔部31的內周面形成有向內側突出的突出部32。此外，在第一構件30的穿孔部31中填充並固化有第二構件20。
第二實施方式的穿孔部31是以在深度方向（Z方向）上開口徑自表面33側朝向底部314變小的縮徑部311、在深度方向上開口徑自表面33側朝向底部314變大的擴徑部312、及在深度方向上開口徑自表面33側朝向底部314變小的縮徑部313相連的方式而形成。縮徑部311是以直線狀縮徑的方式而形成，擴徑部312是以曲線狀擴徑的方式而形成，縮徑部313是以曲線狀縮徑的方式而形成。再者，縮徑部311為本發明的「第二縮徑部」的一例，擴徑部312為本發明的「第二擴徑部」的一例，縮徑部313為本發明的「第三縮徑部」的一例。
此外，自表面33側朝向底部314側依序配置有縮徑部311、擴徑部312及縮徑部313。因此，在穿孔部31中，縮徑部311與擴徑部312的邊界部分的開口徑（內徑）R4變得小於表面33的開口徑R3、及擴徑部312與縮徑部313的邊界部分的開口徑R5。藉此，將突出部32配置於進入底部314側的位置。該突出部32例如是跨周方向上的全長而形成，且形成為環狀。
再者，第一構件30的其他構成與所述的第一構件10相同。 -接合構造體的製造方法-
繼而，參照圖4～圖6，對第二實施方式的接合構造體200的製造方法進行說明。
首先，在第一構件30的表面33形成穿孔部31，並且在該穿孔部31的內周面形成突出部32。該穿孔部31及突出部32例如是如圖5所示，藉由照射一個脈衝由多個次脈衝所構成的雷射而形成。作為具體例，使用所述的光纖雷射雕刻機MX-Z2000或MX-Z2050而形成。再者，在第二實施方式中，與第一實施方式不同，是將突出部32配置於進入底部314側的位置，此種不同例如是由第一構件30的材料或雷射照射條件等的不同所引起。
其後，如圖6所示，將第二構件20鄰接配置於第一構件30的表面33。然後，在對第一構件30及第二構件20進行加壓的狀態下，自第二構件20側向第一構件30的表面33照射接合用的雷射。因此，該雷射的能量在第一構件30的表面33被轉換為熱，第一構件30的表面33的溫度變高。藉此，將第一構件30的表面33附近的第二構件20熔融，而將該第二構件20填充於穿孔部31中。其後，藉由將第二構件20固化，將第二構件20接合於第一構件30，而形成接合構造體200（參照圖4）。
此處，在第二實施方式中，藉由在穿孔部31的內周面形成有向內側突出的突出部32，而容易藉由突出部32將所照射的接合用的雷射封閉於穿孔部31的內部，因此可將接合用的雷射的能量有效率地轉換為熱。藉此，由於可將接合用的雷射的能量抑制為所需最低限度，因此可抑制第二構件20熱劣化。
再者，在將第一構件30及第二構件20鄰接配置時，亦可在第一構件30的表面33或第二構件20的表面設置雷射吸收層（省略圖示）。 -實驗例-
繼而，參照圖7～圖9，對為了確認所述的第二實施方式的效果而進行的實驗例1及實驗例2進行說明。 [實驗例1]
在該實驗例1中，製作對應於第二實施方式的實施例1的接合構造體500（參照圖9）與比較例1的接合構造體，並對各接合構造體的接合強度及第二構件的外觀進行評價。將其結果示於表1。 [表1]
首先，對實施例1的接合構造體500的製作方法進行說明。
在實施例1的接合構造體500中，使用SUS304作為第一構件501的材料，並且使用PMMA（三菱麗陽（Mitsubishi Rayon）製造的ACRYLITE（註冊商標））作為第二構件502的材料。第一構件501是形成為板狀，長度為100 mm，寬度為29 mm，厚度為3 mm。第二構件502是形成為板狀，長度為100 mm，寬度為25 mm，厚度為3 mm。
然後，如圖7所示，對第一構件501的表面的既定區域R照射雷射。該既定區域R是接合接合構造體500的面積，設為12.5 mm×20 mm。另外，該雷射的照射是使用OMRON製造的光纖雷射雕刻機MX-Z2000進行。利用該雷射的加工條件如以下所述。
＜雷射加工條件＞ 雷射：光纖雷射（波長1062 nm） 振盪模式：脈衝振盪（頻率10 kHz） 輸出：3.8 W 掃描速度：650 mm/sec 掃描次數：20次 照射間隔：65 μm 次脈衝數：20
再者，頻率是藉由多個（該例中為20個）次脈衝所構成的脈衝的頻率。即，在該照射條件中，1秒內移動650 mm，並且以65 μm的間隔照射1萬次雷射（脈衝），該脈衝由20個次脈衝所構成。再者，掃描次數是對相同部位重複照射雷射的次數。
如上所述，藉由照射一個脈衝由多個次脈衝所構成的雷射，而在第一構件501的既定區域R形成穿孔部，並且在該穿孔部內將突出部形成於自表面進入的位置。即，如表1所示，開口徑R4（參照圖4）變得小於表面的開口徑R3（參照圖4）及開口徑R5（參照圖4）。
然後，如圖8所示，將第二構件502鄰接配置於第一構件501的既定區域R，在施加既定壓力的狀態下自第二構件502側向既定區域R照射雷射，藉此將第二構件502接合於第一構件501。利用該雷射的接合條件如以下所述。
＜雷射接合條件＞ 雷射：半導體雷射（波長808 nm） 振盪模式：連續振盪 輸出：30 W 焦點直徑：4 mm 掃描速度：1 mm/sec 密合壓力：0.6 MPa
以所述方式製作實施例1的接合構造體500（參照圖9）。
繼而，對比較例1的接合構造體的製作方法進行說明。
在比較例1的接合構造體中，作為第一構件及第二構件的材料，使用與實施例1相同者。此外，在比較例1的接合構造體中，使用無脈衝控制功能的光纖雷射形成穿孔部。即，藉由照射一個脈衝不由多個次脈衝所構成的雷射形成穿孔部。因此，在比較例1的第一構件中形成研缽狀（圓錐狀）的穿孔部。即，如表1所示，在比較例1的第一構件中未形成自內周面向內側突出的突出部，未形成對應於實施例1的開口徑R4及開口徑R5的形狀。另外，在比較例1中，將利用雷射的接合條件設為如以下所述。
＜雷射接合條件＞ 雷射：半導體雷射（波長808 nm） 振盪模式：連續振盪 輸出：100 W 焦點直徑：4 mm 掃描速度：1 mm/sec 密合壓力：0.6 MPa
然後，對實施例1的接合構造體500及比較例1的接合構造體的接合強度及第二構件的外觀進行評價。
再者，接合強度的評價是使用英斯特朗（Instron）製造的機電式萬能試驗機5900進行。具體而言，剪切方向及剝離方向（垂直方向）均以拉伸速度5 mm/min進行試驗，以第二構件的斷裂或接合界面的斷裂結束試驗。此外，在第二構件斷裂的情形時，評價為接合強度合格（○），在接合界面斷裂（剝離）的情形時，評價為接合強度不合格（×）。
另外，接合後的第二構件的外觀的評價是藉由目視進行。具體而言，在第二構件不存在燒焦、變色、變形的情形時評價為合格（○），在第二構件存在燒焦、變色、變形的情形時評價為不合格（×）。
如所述的表1所示，在實施例1的接合構造體500中，剪切方向及剝離方向的接合強度均合格，第二構件502的外觀亦合格。其原因在於：在將第二構件502接合於第一構件501時，容易藉由突出部將所照射的雷射封閉於穿孔部的內部，故而可將雷射的能量有效率地轉換為熱，因此可將雷射的能量抑制為所需最低限度。即，在實施例1的接合構造體500中，可抑制第二構件502的熱劣化。
相對於此，在比較例1的接合構造體中，剪切方向及剝離方向的接合強度均合格，但第二構件產生燒焦，外觀不合格。其原因在於：在將第二構件接合於第一構件時，難以將雷射的能量有效率地轉換為熱，因此將雷射的能量（接合用雷射的輸出）設定為高於實施例1。 [實驗例2]
在該實驗例2中，製作對應於第二實施方式的實施例2的接合構造體與比較例2的接合構造體，並對各接合構造體的接合強度及第二構件的外觀進行評價。將其結果示於表2。 [表2]
在該實驗例2中，變更第一構件的材料而區別於實驗例1。具體而言，在實驗例2的接合構造體中，使用PBT（溫泰克聚合物（WinTech Polymer）製造的DURANEX（註冊商標）3316）作為第一構件的材料。另外，伴隨第一構件的材料的變更，將實施例2的雷射加工條件變更為如以下所述。
＜雷射加工條件＞ 雷射：光纖雷射（波長1062 nm） 振盪模式：脈衝振盪（頻率10 kHz） 輸出：1.1 W 掃描速度：650 mm/sec 掃描次數：3次 照射間隔：65 μm 次脈衝數：3
另外，將實施例2的接合條件變更為如以下所述。
＜雷射接合條件＞ 雷射：半導體雷射（波長808 nm） 振盪模式：連續振盪 輸出：1.0 W 焦點直徑：4 mm 掃描速度：1 mm/sec 密合壓力：0.6 MPa
另外，將比較例2的接合條件變更為如以下所述。
＜雷射接合條件＞ 雷射：半導體雷射（波長808 nm） 振盪模式：連續振盪 輸出：2.5 W 焦點直徑：4 mm 掃描速度：1 mm/sec 密合壓力：0.6 MPa
以所述方式製作穿孔部形成有突出部的實施例2的接合構造體與穿孔部未形成有突出部的比較例2的接合構造體。再者，接合強度及外觀的評價方法與實驗例1相同。
如所述的表2所示，在實施例2的接合構造體中，剪切方向及剝離方向的接合強度均合格，第二構件的外觀亦合格。即，即便在使用樹脂即PBT作為第一構件的材料的情形時，藉由形成具有突出部的穿孔部，亦可將雷射的能量有效率地轉換為熱，因此可將雷射的能量抑制為所需最低限度，故而可抑制第二構件熱劣化。
相對於此，在比較例2的接合構造體中，剪切方向及剝離方向的接合強度均合格，但第二構件產生燒焦，外觀不合格。其原因在於：在將第二構件接合於第一構件時，難以將雷射的能量有效率地轉換為熱，因此將雷射的能量設定為高於實施例2。 （其他實施方式）
再者，此次揭示的實施方式在所有方面均為例示，並非成為限定性解釋的根據。因此，本發明的技術範圍並不僅由所述的實施方式解釋，而是基於申請專利範圍的記載而劃定。另外，在本發明的技術範圍中，包括與申請專利範圍相同的含義及範圍內的全部變更。
例如，在第一實施方式中，表面13可平坦，亦可彎曲。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了以擴徑部111與縮徑部112相連的方式形成的例，但並不限於此，亦可在擴徑部與縮徑部之間形成沿深度方向筆直延伸的部分。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了穿孔部11的周圍平坦的例，但並不限於此，亦可如圖10所示的第一變化例的第一構件10a般，在穿孔部11的開口的周圍形成有自表面13向上方隆起的隆起部14。隆起部14是以包圍穿孔部11的周圍的方式形成，在俯視下形成為大致圓形。該隆起部14例如在照射一個脈衝由多個次脈衝所構成的雷射時，藉由堆積經熔融的第一構件10a而形成。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了穿孔部11的軸心垂直於表面13的例，但並不限於此，亦可如圖11所示的第二變化例的第一構件10b般，以穿孔部11b的軸心相對於表面13傾斜的方式而形成。在穿孔部11b的內周面形成有向內側突出的突出部12b。該穿孔部11b例如是藉由使雷射的照射方向相對於表面13傾斜（45°以上且小於90°）的方式而形成。藉此，即便在形成穿孔部11b的區域的上方存在照射雷射時的障礙物的情形時，亦可形成穿孔部11b。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了在穿孔部11形成一個突出部12的例，但並不限於此，亦可如圖12所示的第三變化例的第一構件10c般，在穿孔部11c形成有多個突出部121c及突出部122c。該穿孔部11c例如可變更雷射的輸出條件，藉由對相同部位照射雷射而形成。若以此種方式構成，則由於穿孔部11c的表面積變大，因此可將接合用的雷射的能量更有效地轉換為熱。再者，在圖12中，突出部是121c及122c的兩個部位，但亦可形成三個部位以上。再者，第二實施方式亦為同樣。
另外，亦可如圖13所示的第一實施方式的第四變化例的第一構件10d般，藉由位置錯開的多次雷射照射而形成一個穿孔部11d。即，亦可使藉由雷射照射而形成的穿孔部的一部分重疊，藉此而形成一個穿孔部11d。在穿孔部11d的內周面形成有向內側突出的突出部12d。再者，第二實施方式亦為同樣。另外，亦可適當組合所述的第一變化例～第四變化例。 [產業上之可利用性]
