  However, in the absorbent article disclosed in Patent Literature 1, when the excrement of the wearer reaches the inspection member, the excrement of the wearer covers at least a part of the inspection member or overlaps with the inspection member. Sometimes. When the display unit is hidden by the excrement covering the inspection member, the wearer cannot visually recognize the display unit and cannot check the health condition. Further, even if the wearer can visually recognize the display unit via the excrement that overlaps the display unit, there is a possibility that the color of the display unit is erroneously recognized based on the color of the excrement. Thus, there is a possibility that the wearer may not be able to grasp the exact health condition based on the excrement.

  Therefore, there is a demand for an absorbent article that is provided with an inspection member for inspecting the health condition of the wearer and that allows the wearer to easily grasp the exact health condition.

  The absorbent article according to the present disclosure has a front-rear direction, a width direction orthogonal to the front-rear direction, a thickness direction orthogonal to the front-rear direction and the width direction, and a horizontal direction parallel to the front-rear direction and the width direction.

(1) Outline of Embodiment At least the following matters will be apparent from the description of the present specification and the accompanying drawings.

  The absorbent article according to one aspect has a front-rear direction, a width direction perpendicular to the front-rear direction, a thickness direction perpendicular to the front-rear direction and the width direction, and a horizontal direction parallel to the front-rear direction and the width direction. A direction, an absorbent core containing an absorbent material, a backsheet arranged on a non-skin side than the absorbent core, and an inspection member for inspecting a health condition of a wearer. The inspection member is arranged on the skin surface side of the back sheet in the thickness direction. The inspection member has a display unit including an indicator that changes color based on a detection target included in the excrement. The display unit is visible from the back sheet side. A hydrophobic portion having hydrophobicity is arranged in an extension region extending from the display portion in the thickness direction and the horizontal direction on the skin surface side of the back sheet.

When the hydrophobic portion is disposed in an extension region extending in the thickness direction from the display portion, a diffusion path through which excreta excreted on the skin side of the absorbent article is diffused toward the display portion in the thickness direction. above,
There is a hydrophobic part. Since the hydrophobic part has hydrophobicity, it is easy to suppress the water-soluble excrement from diffusing to the display part side. Further, when the hydrophobic portion is disposed in an extension region extending in the horizontal direction from the display portion, on the diffusion path in which the excrement diffused into the absorbent article is diffused in the horizontal direction toward the display portion, There are hydrophobic parts. The hydrophobic part is easy to suppress the water-soluble excrement from diffusing to the display part side. Further, even when the display unit is not arranged in a range where the excrement reaches while wearing the absorbent article, the excrement may reach the display unit due to unexpected movement of the wearer. is there. Even in such a case, it is easy to suppress the excrement from reaching the display unit by the hydrophobic part arranged in the extension area. As described above, it is easy to suppress the excrement from covering or overlapping the display unit, and it is easy to ensure the visibility of the display unit. Accordingly, when the wearer visually recognizes the display unit from the back seat side, the wearer can easily grasp the correct health condition.

  According to this aspect, the absorbent article includes the top sheet that is disposed closer to the skin surface than the absorbent core and has an absorbent region overlapping the absorbent core in the thickness direction. The hydrophobic part disposed in the extension region is disposed in a range where the excrement discharged in the absorption region reaches. This can prevent the excrement reaching the hydrophobic part from being diffused to the display part side, so that the visibility of the display part can be easily secured. Accordingly, when the wearer visually recognizes the display unit from the back seat side, the wearer can easily grasp the correct health condition.

  According to this aspect, the hydrophobic part is in contact with the display part. Thereby, it is possible to suppress the excrement from reaching the display unit. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

  According to this aspect, the hydrophobic portion is in contact with the skin-side surface of the display unit. Thereby, it is possible to suppress the excrement diffusing from the skin surface side to the non-skin surface side from reaching the display unit. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

  According to this aspect, the hydrophobic portion is in contact with the surface on the non-skin side of the display unit. Thereby, it is possible to suppress the excrement from reaching the surface of the display section visually recognized from the back sheet side. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

  According to this aspect, the inspection member is disposed between the absorbent core and the back sheet in the thickness direction. In the thickness direction, a sheet-like sheet member is arranged as the hydrophobic portion between the absorbing core and the display unit. Since the sheet member is disposed between the absorbent core and the display unit, it is possible to suppress the excrement diffused from the skin surface side to the non-skin surface side from reaching the display unit. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

  According to this aspect, the absorbent article 1 has an excretion port contact portion that contacts the excretion port of the wearer. In a plan view in the thickness direction, the hydrophobic portion is closer to the center of the excretion opening contact portion than the display portion. Since the hydrophobic part is closer to the center of the excretion port contact part than the display part, the hydrophobic part exists on the diffusion path in which the excrement excreted in the excretion port contact part diffuses toward the display part. The hydrophobic part can suppress the excrement diffused from the excretion opening contact part toward the display part from reaching the display part. Thereby, the visibility of the display unit can be secured, and the wearer can easily grasp the correct health condition.

  According to this aspect, the absorbent article 1 has a skin-side member disposed closer to the skin than the display unit. The skin surface side member is a region that does not overlap with the display unit in the thickness direction, and has a background region that is visible from the back sheet side. The color of the display unit is a color having a hue difference of 120 degrees or more in a hue circle with respect to the color of the background area. Thus, the display portion is visually recognized by being emphasized by the color of the background region. This makes it easier for the wearer to visually recognize the display unit, so that the wearer can easily grasp the correct health condition.

  According to this aspect, the color of the display section is a color having a hue difference of 120 degrees or more in hue circle angle with respect to the color of the excrement. Thereby, the display portion is visually recognized with the display portion highlighted by the color of the excrement. This makes it easier for the wearer to visually recognize the display unit, so that the wearer can easily grasp the correct health condition.

  According to this aspect, the absorbent article 1 has a skin-side member disposed closer to the skin than the display unit. The skin surface side member is a region that does not overlap with the display unit in the thickness direction, and has a background region that is visible from the back sheet side. The color of the background area is a color having a hue difference of 45 degrees or less in the hue circle with respect to the color of the excrement. Even if the excrement permeates the skin-side member, the color of the background area is a color whose hue difference is not more than 45 degrees in the hue circle angle with respect to the color of the excrement, so that the excrement is inconspicuous. This makes it easier for the wearer to visually recognize the display unit without being distracted by the color of the excrement, thereby making it easier to grasp an accurate health condition.

(2) Schematic Configuration of Absorbent Article Hereinafter, an outline of the absorbent article according to the embodiment will be described with reference to the drawings. The absorbent article may be an absorbent article such as a sanitary napkin, panty liner, incontinence pad, stool pad. The absorbent article may be an article used by being attached to the inside of a wearing article such as underwear. The absorbent article 1 of the present embodiment is a sanitary napkin.

  In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and ratios of dimensions may be different from actual ones. Therefore, specific dimensions and the like should be determined in consideration of the following description. In addition, there may be a case where parts having different dimensional relationships and ratios between drawings are included.

  FIG. 1 is a plan view of the absorbent article according to the embodiment as viewed from the skin surface side. FIG. 2 is a plan view of the absorbent article according to the embodiment as viewed from the non-skin side. FIG. 3 is a cross-sectional view of the absorbent article according to the embodiment. Specifically, FIG. 3 is a cross-sectional view along the line AA shown in FIG. The “skin side” corresponds to the side facing the wearer's skin during wearing (during use). “Non-skin side” corresponds to the side that is turned away from the wearer's skin during wearing (during use).

  As shown in FIGS. 1 and 2, the absorbent article 1 has a front-rear direction L and a width direction W. The front-rear direction L is a direction extending from the front side (abdominal side) to the rear side (back side) of the wearer, or a direction extending from the rear side of the wearer to the front side. The width direction W is a direction orthogonal to the front-rear direction L. The absorbent article has a thickness direction T extending to the skin side T1 and the non-skin side T2. Further, the absorbent article has a horizontal direction that is parallel to the front-rear direction L and the width direction W.

  In this specification, the outer edge is an outer edge in the width direction, and the inner edge is an inner edge in the width direction.

  The absorbent article 1 has a central area S3, a front area S1, and a rear area S2. The central area S3 is an area having an excretion port contact portion that contacts an excretion port (for example, a vaginal opening) of the wearer. When the absorbent article is worn on the wearing article (for example, underwear), the central region S3 is located at the crotch of the wearing article. That is, the central region is a region located between the wearer's crotch, that is, between the wearer's feet. In the embodiment in FIG. 1, the central region S3 is a region where the wings 14 for fastening the absorbent article 1 to the wearing article are provided. The front side area S1 is located on the front side of the central area S3. The rear area S2 is located behind the central area S3.

  As shown in FIGS. 1 and 2, the absorbent article 1 may include an absorbent article main body 10 configured by members other than the inspection member 60, and an inspection member 60. The absorbent article main body 10 may correspond to a general absorbent article such as a sanitary napkin that does not include the inspection member 60. That is, the absorbent article main body 10 may correspond to the absorbent article 1 having no inspection member 60.

  The absorbent article main body 10 may be composed of a main body 12 and a pair of wings 14. The main body 12 has an absorbent core 20. The main body portion 12 is a portion inside the wing 14 in the width direction W. The pair of wings 14 extend from the main body 12 to the outside in the width direction W, and are fixed to the non-skin side T2 of the wearing article when attached to the wearing article. The boundary between the main body 12 and the wing 14 is a fold FL extending in the front-rear direction L.

  The absorbent article 1 includes an absorbent core 20, a back sheet 40, and an inspection member 60. Further, the absorbent article 1 may include the top sheet 30, the side sheet 50, and the adhesive section 70.

  The absorbent core 20 includes an absorbent material that absorbs liquid. Absorbent materials can be formed, for example, from hydrophilic fibers, pulp and superabsorbent polymers (SAP). The absorbent core 20 may be wrapped by a core wrap (not shown). The core wrap only needs to cover the absorbent core 20 at least on the skin-facing surface side of the absorbent core 20. As a specific example, the core wrap may include a sheet disposed on the skin side of the absorbent core 20 and a sheet disposed on the non-skin side of the absorbent core 20. The absorbent core 20 may not be covered by the core wrap.

  The absorbent core 20 is arranged at least in the central area S3. The absorber core may extend from the central area S3 to the front area S1. The absorber core may extend from the central area S3 to the rear area S2.

  The topsheet 30 is arranged on the skin side with respect to the absorbent core 20. The top sheet 30 has an absorption region AR overlapping the absorption core in the thickness direction T.

  The top sheet 30 has liquid permeability. The topsheet 30 may be made of any sheet-like material having a structure that allows liquid to pass through, such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, or a mesh sheet. As the material of the woven or nonwoven fabric, any of natural fibers and chemical fibers can be used.

  The back sheet 40 is arranged on the non-skin side with respect to the absorbent core 20. The back sheet 40 may have liquid impermeability.

  The back sheet 40 has transparency. Thereby, as shown in FIG. 3, even if the inspection member 60 is disposed on the skin surface side T1 with respect to the back sheet 40 in the thickness direction T, as shown in FIG. It is possible.

  In the present invention, the term “visible” refers to a distance of about 30 to 50 cm in a room (approximately 500 to 750 lx (lux)) brightly illuminated with daylight white (color temperature reference 4600 to 5400 K (Kelvin)). This means that a subject having good visual acuity (1.0 or more) with both eyes can visually recognize the subject when viewing it.

  The transparency of the backsheet 40 can be specified by the opacity (OP). The backsheet 40 is completely transparent if it has 0% opacity. On the other hand, when the back sheet 40 has 100% opacity, it does not have transparency, that is, the back sheet 40 does not transmit light. Therefore, the opacity of the back sheet 40 is less than 100%. The opacity of the back sheet 40 may be 50% or less so that the inspection member 60 (the display unit 64) can be visually recognized more accurately. The opacity of the back sheet 40 may be 8.5% or less in order to more accurately view the color of the display unit 64.

  In order to determine the opacity, a dispersion colorimeter may be used. For example, a dispersion colorimeter is available from BYK-Gardner GmbH (Geretsried, Germany) under the trade name “BYK-Gardner Color-Guide 45/0” ( Catalog No. 6800). The measurement can be performed at a viewing angle of 2 ° (degrees) using the light source “A”. The dispersion colorimeter comprises a light source for illuminant A (ie, something similar to an incandescent lamp having a correlated color temperature of about 3000 K), a flat table, a white standard plate, a standard black plate, a multi-cell light source. A photodetector comprising a detector diode array; and a computer. White and black standard plates are available from the company under catalog numbers 6811 and 6810, respectively.

  When measuring, place the white standard plate on a flat table. The sample material is placed flat on a white standard plate. The sample material is irradiated with a light source having an incident angle of 45 °. Light reflected from the sample material is received by a photodetector at a light receiving angle of 0 °. The reflectance (Yw) of the reflected light is detected by a photodetector. Similarly, after placing the black standard plate on a flat table, the sample material is placed flat on the black standard plate. The sample material is irradiated with a light source having an incident angle of 45 °. Light reflected from the sample material is received by a photodetector at a light receiving angle of 0 °. The reflectance (Yb) of the reflected light is detected by a photodetector.

  The opacity (OP) can be determined by the following equation.

    OP (%) = (Yb / Yw) × 100

  This process is repeated at least five times for one sample sheet material, and the average value of the measured opacity (OP) is calculated and recorded with a colorimeter. The average value of the measured opacity is called the opacity of the sheet material.

  The back sheet 40 is made of a material such as a sheet in which a breathable resin film is joined to a nonwoven fabric such as a laminated nonwoven fabric mainly composed of polyethylene sheet or polypropylene, a breathable resin film, spunbond, or spunlace. Good.

  The backsheet 40 is subjected to a heat compression process of compressing the backsheet 40 in the thickness direction T while heating over the entire area of the surface of the nonwoven fabric (for example, SMS (spunbond / meltblown / spunbond)). May be. Thereby, a high-density portion may be formed on the back sheet 40. The heat compression process for forming the high-density portion is performed by subjecting the back sheet 40 (nonwoven fabric) to a known pressure process such as a calendering process or an embossing process. In the high-density portion, the fibers on the surface of the nonwoven fabric are compacted, so that fine irregularities on the surface are reduced and the surface is in a smooth state as compared with a region where the high-density portion is not formed. By the heat compression process, the back sheet 40 may have transparency. In addition, by using the backsheet 40 made of the nonwoven fabric that has been subjected to the treatment, a zipper sound is less likely to be generated when the absorbent article 1 is opened, and it is difficult for others to notice when using the absorbent article 1.

  The side sheet 50 may cover an outer edge of the top sheet 30. The side sheet 50 may cover the outer edge of the top sheet 30 in the width direction W, and may extend outside the top sheet 30 in the width direction W. Note that the absorbent article 1 may not have the side sheet 50.

  The side sheet 50 can be made of the same material as the top sheet 30. However, in order to prevent the bodily fluid attached to the top sheet 30 from crossing the side sheet 50 and leaking out of the absorbent article 1 in the width direction W, the side sheet 50 has hydrophobicity or water repellency. May have. The side sheet 50 may be disposed on the outer edge of the absorbent core 20 in the width direction W, the wing 14 described later, and the flap portion 80 described later.

  The inspection member 60 is a member for inspecting a wearer's health condition. The inspection member 60 displays the health condition (color indicating) of the wearer with an indicator. In the present embodiment, for examining a health condition, for example, an immunochromatography method or a test paper method can be used.

  The immunochromatography method is performed by dropping excrement (for example, blood) onto a member (for example, a cellulose membrane) on which labeled particles containing antibodies are spread. When the excrement contains a detection target (specifically, a target component (eg, an antigen) to be detected), the detection target and the antibody cause an antigen-antibody reaction to form a complex. . The formed complex moves on the membrane by capillary action. A different type of antibody (indicator) is linearly arranged at the destination of the complex. The complex is colored by binding to another type of antibody. The presence or absence of coloration (color change) indicates the health condition of the wearer. The wearer can confirm the health condition by visually determining the presence or absence of coloration.

  In the test paper method, a color is formed by the indicator contained in the inspection member 60 reacting with the detection target contained in the excrement. The presence or absence of coloration (change in the color of the indicator) indicates the health condition of the wearer. The wearer can visually confirm the coloration (change in the color of the indicator) by the indicator to confirm the health condition.

  Excretions include, for example, blood, urine, stool, sweat, vaginal discharge, and the like. Items indicating health status include, for example, physical condition-related (pH, iron deficiency anemia, renal function, myocardial infarction, inflammation / infection, nutritional status evaluation, etc.), pregnancy-related (physiological cycle prediction, ovulation prediction, etc.), mental-related (Depression, drugs, etc.). The detection target is, for example, urine waste (urine specific gravity), leukocyte, hydrogen ion (pH), protein, glucose, ketone body, urobilinogen, bilirubin, urinary occult blood, nitrite, steroid, peptide, aromatic compound, FSH ( Follicle stimulating hormone), BUN (Urea nitrogen), AlB (Albumin), LPS (lipopolysaccharide), hCG (human chorionic gonadotropin), LH (luteinizing hormone), U-ALB, CRP (C-reactiv protein), Examples include myoglobin, CK-MB, troponin I, troponin T, hemoglobin, strep A, HBs antibody, HIV antibody, TP antibody, rotavirus, influenza virus, adenovirus, DNA, O-157, cocaine, marijuana, morphine, and the like. No.

  The inspection member 60 has a contact part 62 and a display part 64. The contact part 62 is a part for making excretion contact. The display unit 64 is a part that displays the health state (color indicating) of the wearer. The display unit 64 includes an indicator that changes color based on the detection target contained in the excrement that has come into contact with the contact unit 62. The indicator is a chemical substance (inorganic substance, organic substance) that is colored by reacting with a detection target or a substance derived from the detection target (for example, a complex).

  For example, in the immunochromatography method, the contact portion 62 is a portion that guides excrement (test target) to a region where the labeled particles including the antibody are arranged. The contact portion 62 may include a region where the label particles are arranged. When the excrement contacts the contact portion 62, the detection target (antigen) and the antibody contained in the excretion cause an antigen-antibody reaction to form a complex. The display unit 64 includes a region (detection line) in which an indicator (another type of antibody) that is colored by binding to the complex is arranged. Therefore, when the immunochromatography method is used, the contact section 62 and the display section 64 are arranged at different positions. Therefore, in this case, the contact section 62 and the display section 64 are different.

  Note that the test member 60 may include a control line that is a region that shows color regardless of the presence or absence of the target antigen to be detected when the test is appropriate. The control line is located farther from the contact section 62 than the detection line (display section 64).

  On the other hand, in the test paper method, the contact portion 62 includes at least a region where the indicator is arranged. Since the indicator contained in the contact part 62 reacts with the detection target to give a color, the contact part 62 and the display part 64 are arranged at the same position. Therefore, in this case, the contact portion 62 and the display portion 64 are the same.

  As described above, when the immunochromatography method is used, the contact portion 62 includes the label particles, and the display portion 64 includes the indicator for displaying the health condition of the wearer. When the test strip method is used, the contact part 62, that is, the display part 64, includes an indicator for displaying the health condition of the wearer.

  In addition, when the contact part 62 is provided only to guide the excrement (detection target) to the display part 64, the contact part 62 may not include the indicator.

  The inspection member 60 may be any member that can hold or contain the indicator. The inspection member 60 can be made of any material such as paper, nonwoven fabric, and woven fabric. The rigidity of the inspection member 60 may be equal to or less than the rigidity of the member used for the absorbent article 1. Thereby, even if the absorbent article 1 is provided with the inspection member 60, it becomes easy to suppress deterioration of the touch of the wearer. As shown in FIG. 1 and the like, the inspection member 60 may be, for example, a linear plate shape.

  Note that, in a horizontal direction that is a direction along the front-rear direction L and the width direction W (that is, a plan view in the thickness direction T), the maximum range of the reaching range is equal to the absorption region AR in general use. This is an area that overlaps with at least one of the liquid-permeable sheets that directly or indirectly comes into contact with the top sheet 30 into which excreted excrement can diffuse. Note that a liquid-permeable sheet that comes into “indirect” contact with the top sheet 30 means that it is in contact with the top sheet 30 via another liquid-permeable sheet. The excrement excreted in the top sheet 30 can be diffused to the liquid permeable sheet via another liquid permeable sheet. On the other hand, in the thickness direction T (that is, the cross section of the absorbent article 1), the maximum range of the reaching range is a range from the surface of the skin side T1 of the top sheet 30 to the surface of the skin side T1 of the back sheet 40. It is.

  At least a part of the contact portion 62 only needs to be arranged within the maximum range of the reach. At least a part of the contact portion 62 is disposed at a position overlapping the top sheet 30 in the thickness direction T or at a position overlapping the absorbent core 20 so that the excrement easily reaches the contact portion 62. , May be arranged in the central area S3, or may be arranged in the range of the excretion opening contact portion that contacts the excretion opening of the wearer. Thereby, the excrement excreted from the wearer can be brought into contact with the contact portion 62. Therefore, the indicator contained in the display unit 64 can be colored, and the display unit 64 can display the health condition.

  At least a portion of the contact portion 62 may be in contact with the absorbent core. Since the excrement is excreted in the absorbent core 20, more excretion can be brought into contact with the contact portion 62. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved. A part of the contact portion 62 is in contact with the absorbent core 20.

  Further, at least a part of the contact portion 62 may overlap the absorbent core 20 in the thickness direction T. Since the excrement is excreted in the absorbent core 20, more excretion can be brought into contact with the contact portion. Thus, the indicator can be colored based on many detection targets, and the inspection accuracy can be improved. Part of the contact portion 62 overlaps the absorbent core 20 in the thickness direction T. The rest of the contact portion 62 does not overlap with the absorbent core 20 in the thickness direction.

  The inspection member 60 may be fixed (joined) to at least one of the absorbent core 20, the top sheet 30, the back sheet 40, and the side sheet 50. The inspection member 60 may be fixed by, for example, an adhesive (for example, a hot melt adhesive (HMA)) for joining the materials of the absorbent article 1 together. In the inspection member 60, at least one of the contact portion 62 and the display portion 64 may be fixed. In the inspection member 60, at least a part of the contact part 62 may be fixed, and at least a part of the display part 64 may be fixed. The inspection member 60 may have a portion other than the contact portion 62 and the display portion 64 fixed. For example, the inspection member 60 may have a fixed part configured by at least a part of the part other than the contact part 62 and the display part 64. It may be fixed by an adhesive applied on the fixing part. By fixing the inspection member 60, it is possible to prevent the contact portion 62 from moving outside the reach.

  The adhesive section 70 is an area provided with an adhesive for fixing the absorbent article 1 to the wearing article 100. The adhesive section 70 is disposed on the non-skin side T2 of the back sheet 40 and is for fixing the absorbent article 1 to a worn article (for example, underwear) 100.

  As shown in FIG. 2, the adhesive section 70 may include a central adhesive section 72 and side adhesive sections 74. The center adhesive portion 72 is disposed on the non-skin side T2 of the back sheet 40 in the main body 12. The central adhesive portion 72 has an adhesive for fixing the main body 12 to the wearing article 100. The side adhesive portion 74 is arranged on the non-skin side T2 of the back sheet 40 on the wing 14. The side adhesive portion 74 has an adhesive for fixing the wing 14 to the wearing article 100.

  The adhesive section 70 may have transparency. In FIG. 2, the central adhesive portion 72 overlaps (a part of) the display portion 64 in the thickness direction T. For this reason, the central adhesive portion 72 may have transparency. The adhesive section 70 may have transparency by being made of, for example, HMA.

  As shown in FIGS. 1 to 3, the absorbent article 1 includes a hydrophobic portion 90 having hydrophobicity. The hydrophobic portion 90 is disposed in an extension region ER extending in the thickness direction T and the horizontal direction from the display portion 64 on the skin surface side with respect to the back sheet 40.

  When the hydrophobic portion 90 is disposed in the extension region ER extending from the display portion 64 in the thickness direction T, the excrement excreted on the skin surface side T1 of the absorbent article 1 is displayed in the thickness direction T on the display portion. The hydrophobic portion 90 exists on a diffusion path that diffuses toward 64. Since the hydrophobic part 90 has hydrophobicity, it is easy to suppress the water-soluble excrement from diffusing to the display part 64 side. When the hydrophobic part 90 is arranged in the extension region ER extending in the horizontal direction from the display part 64, the excrement diffused inside the absorbent article 1 is diffused in the horizontal direction toward the display part 64. The hydrophobic part 90 exists on the diffusion path. The hydrophobic part 90 can easily suppress the water-soluble excrement from diffusing to the display part 64 side. As described above, it is easy to suppress the excrement from covering the display unit 64 or overlapping the display unit 64, and it is easy to ensure the visibility of the display unit 64. Accordingly, when the wearer visually recognizes the display unit 64 from the back sheet 40 side, the wearer can easily grasp the correct health condition.

  As in the present embodiment, the hydrophobic portion 90 arranged in the extension region ER may be arranged in a range where the excrement excreted in the absorption region AR reaches. This can suppress the excrement reaching the hydrophobic part 90 from being diffused to the display part 64 side, so that the visibility of the display part 64 can be easily secured. Thereby, when the wearer visually recognizes the display unit 64 from the back seat side, it becomes easier for the wearer to grasp an accurate health condition.

  As shown in FIG. 3, the hydrophobic part 90 may be in contact with the display part 64. It is possible to suppress the excrement from reaching the display unit 64. Thereby, the visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

  The hydrophobic portion 90 disposed in the extension region ER includes a skin-side hydrophobic portion 92 disposed on the skin surface side T1 with respect to the display portion 64 and a non-skinned portion disposed on the non-skin surface side T2 with respect to the display portion 64. It may have a skin-side hydrophobic portion 94 and a side-surface-side hydrophobic portion 96 disposed outside the display portion 64 in the horizontal direction (the width direction W in FIG. 3).

  The skin side hydrophobic portion 92 which is the hydrophobic portion 90 may be in contact with the surface of the display portion 64 on the skin side. Thereby, it is possible to suppress the excrement that diffuses from the skin surface side T1 to the non-skin surface side T2 from reaching the display unit 64. The visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

  The non-skin side hydrophobic portion 94 which is the hydrophobic portion 90 may be in contact with the skin side surface of the display portion 64. Thereby, it is possible to suppress the excrement from reaching the surface of the display section 64 visually recognized from the back sheet side. The visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

  The side surface side hydrophobic portion 96 that is the hydrophobic portion 90 may be in contact with the side surface of the display unit 64. Thereby, it is possible to suppress the excrement diffused in the horizontal direction from reaching the display unit 64. The visibility of the display unit 64 can be ensured, and the wearer can easily grasp the correct health condition.

  As shown in FIG. 3, the hydrophobic part 90 may cover the periphery of the display part 64. Therefore, the hydrophobic portion 90 may be arranged in a region different from the extension region ER. The hydrophobic part 90 may cover the entire surface of the display part 64. The hydrophobic part 90 may cover a part of the display part 64. The hydrophobic part 90 may cover a part of the contact part 62. The hydrophobic part 90 does not cover the entire surface of the contact part 62 so that the excrement reaches the contact part 62.

  The hydrophobic part 90 can be constituted by a layer or a member having hydrophobicity. For example, a water-repellent layer as the hydrophobic portion 90 may be provided by applying a water-repellent to a part of the contact portion 62 with a water-repellent spray, a coating device, or the like. The member constituting the display unit 64 may be impregnated with a water repellent. A portion to which the water repellent is not to be attached (for example, (a part of) the contact portion 62) may be covered with a masking tape or the like. After covering the contact portion 62 with the hydrophobic portion 90, the contact portion 62 may be exposed by peeling off a masking tape or the like. The water repellent may be a silicone water repellent or a fluorine water repellent. It is preferable that the water repellent (hydrophobic portion 90) does not easily discolor.

  The hydrophobic part 90 may be made of the same material as the back sheet 40. The hydrophobic part 90 may be formed of a bonding layer (for example, a hot melt adhesive (HMA)) for bonding the members constituting the absorbent article 1. Thereby, the inspection member 60 can be fixed and the hydrophobic portion 90 can be formed.

  The hydrophobic part 90 may have transparency. For example, the non-skin side hydrophobic portion 94 may have transparency in order to make the coloration easily visible. On the other hand, since the skin-side hydrophobic portion 92 is disposed closer to the skin surface T1 than the display portion 64, the skin-side hydrophobic portion 92 does not need to have transparency, and may have transparency. Further, the side surface side hydrophobic portion 96 does not need to have transparency, and may have transparency.
