The auxiliary slit 54 constituting the front marker portion extends outward in the width direction W toward the front side, and is arranged along the wearer's inguinal region. The inguinal region is difficult to be hidden by clothing or absorbent articles being worn, and is easily visible to the wearing assistant located on the side of the wearer. Therefore, when mounting, the auxiliary slit 54 can be aligned with the inguinal region of the wearer to align the absorbent article 10 at an appropriate position. Further, after mounting, the auxiliary slit 54 can be visually recognized from the non-skin surface side T2 of the absorbent article 10 to confirm whether the auxiliary slit 54 is in a position corresponding to the inguinal region. Therefore, the wearing assistant can grasp whether or not the absorbent article is mounted at the correct position from the non-skin surface side of the absorbent article.

Further, since the front mark portion is the auxiliary slit 54, the absorption core 50 is easily deformed with the auxiliary slit 54 as a base point when worn. Therefore, the auxiliary slit 54 can be aligned with the inguinal region, and the auxiliary slit 54 can be arranged along the inguinal region. Therefore, the absorbent article can be aligned at an appropriate position, and the absorbent core 50 can be arranged along the inguinal region. Further, as shown in FIG. 6, the absorption core 50 is deformed with the auxiliary slit 54 as a base point, so that wrinkles are generated around the auxiliary slit 54 on the skin surface and the non-skin surface of the absorbent article 10.

As shown in FIG. 5, the skin surface sheet 41 and the non-skin surface sheet 42 may be joined in a region overlapping the auxiliary slit 54. In the present embodiment, the core wrap 56 as the skin surface sheet 41 and the core wrap 56 as the non-skin surface sheet 42 are joined in a region overlapping with the auxiliary slit 54. By joining the skin surface sheet 41 and the non-skin surface sheet 42, the auxiliary slit 54 comes into close contact with the skin surface sheet 41 and the non-skin surface sheet 42, and the visibility of the auxiliary slit 54 is improved. By improving the visibility of the front marker portion, it becomes easier to align the absorbent article in an appropriate position.

Further, in order to improve the visibility of the auxiliary slit 54, the inner edge and the outer edge of the auxiliary slit 54 may be pressed in the thickness direction T. By pressing the inner and outer edges of the auxiliary slit 54, the visibility of the edge of the auxiliary slit 54 can be enhanced, and the visibility of the front marker portion can be enhanced.

The absorption core 50 may have an inseam marker. The inseam mark portion is a mark for aligning with the inseam of the wearer when worn, and is visible from the skin surface side T1 and the non-skin surface side T2 of the absorbent article. The inseam mark portion of the present embodiment is formed in the absorption core 50 and is composed of a side slit 52. The side slit 52 as the inseam marker portion is configured to be visible from the skin surface side T1 of the absorbent article 10 via the skin surface sheet 41, and the non-skin of the absorbent article 10 via the non-skin surface sheet 42. It is configured to be visible from the surface side T2.

The inseam mark portion of the present embodiment is configured by the side slit 52, but the inseam mark portion is not limited to this. The inseam mark portion may have a configuration that can be visually recognized from the skin surface side T1 and the non-skin surface side T2 of the absorbent article 10, and the absorption material of the absorption core 50 has a low basis weight region where the basis weight is lower than the surrounding area. It may be composed of at least one of a squeezed portion in which the core 50 is compressed in the thickness direction T, a slit formed in the absorption core 50, and a difference in rigidity of the absorption core 50.

The side slit 52 may be arranged at least in the inseam region S3. The front end edge 52F of the side slit 52 may be arranged in the inseam area S3, and the rear end edge 52R of the side slit 52 may be arranged in the inseam area S3. The side slit 52 may extend at least in the front-rear direction L, may be along the front-rear direction L, or may have a portion inclined with respect to the front-rear direction L. The length of the side slit 52 in the width direction W may be constant or may change. The side slits 52 may not be provided at the center of the absorption core 50 in the width direction W, but may be provided in pairs symmetrically with respect to the center of the absorption core 50 in the width direction W.

By providing the side slit 52 in the absorption core 50, it is possible to perform positioning with respect to the body by the side slit 52 on the inseam side of the inguinal region. The side slit 52 extends in the front-rear direction L, which makes it easy to arrange the inseam region S3 along the front-rear direction L of the body at the time of wearing. In addition, after mounting, it is possible to grasp whether or not the inseam region S3 is correctly arranged from the non-skin surface side T2 of the absorbent article 10. The auxiliary slit 54 extends outward in the width direction W, and the side slit 52 extends in the front-rear direction L. Since the auxiliary slit 54 and the side slit 52 extend in different directions, the boundary thereof is easily conspicuous. Therefore, it becomes easy to grasp the area to be arranged along the inguinal region, and it becomes easy to align the absorbent article 10 in an appropriate position.

Further, since the inseam mark portion is the side slit 52, the absorption core 50 is easily deformed with the side slit 52 as a base point when worn. Specifically, when the absorbent article 10 is worn, the absorbent article 10 is sandwiched between both legs, so that the inseam region S3 is subjected to a force toward the inside of the width direction W by the legs. When a force is applied to the absorber in the inseam region S3 toward the inside of the width direction W, the side slit 52 of the absorption core 50 is deformed, the second region R2 moves inside the width direction W, and the width direction of the absorption core 50 The length of W becomes shorter. The absorption core 50 can enter the inside in the width direction by the side slit 52 in the inseam region S3. Since the length of the absorption core 50 in the inseam region S3 in the width direction is short, the absorption core 50 can be easily fitted in the crotch, and a feeling of strangeness when worn can be suppressed. Therefore, the inseam region S3 can be arranged in the region between both legs while being positioned with respect to the inseam by the side slit 52. Therefore, the absorbent article can be aligned in an appropriate position and the absorbent core can be arranged in a more suitable compact state.

As shown in FIG. 4, the skin surface sheet 41 and the non-skin surface sheet 42 may be joined in a region overlapping the side slit 52. In the present embodiment, the core wrap 56 as the skin surface sheet 41 and the core wrap 56 as the non-skin surface sheet 42 are joined in a region overlapping with the side slit 52. By joining the skin surface sheet 41 and the non-skin surface sheet 42, the side slits 52 come into close contact with the skin surface sheet 41 and the non-skin surface sheet 42, and the visibility of the side slits 52 is improved. By improving the visibility of the side slit 52, it becomes easier to align the absorbent article in an appropriate position.

Further, in order to improve the visibility of the side slit 52, the inner edge and the outer edge of the side slit 52 may be pressed in the thickness direction T. By pressing the inner and outer edges of the side slit 52, the visibility of the edge of the side slit 52 can be enhanced, and the visibility of the inseam mark can be enhanced.

The width of the auxiliary slit 54 may be shorter than the width of the side slit 52. The width of the side slit 52 is the length in the direction orthogonal to the longitudinal direction of the side slit 52, and the width of the side slit 52 extending in the front-rear direction L is the length in the width direction. Similarly, the width of the auxiliary slit 54 is the length in the direction orthogonal to the longitudinal direction of the auxiliary slit 54, and in the case of the auxiliary slit 54 extending in the front-rear direction L, it is the length in the width direction. In the form in which the side slit 52 and the auxiliary slit 54 are integrated, the boundary between the side slit 52 and the auxiliary slit 54 may be a portion where the width changes. In the configuration in which the width of the side slit 52 and the width of the auxiliary slit 54 change, the maximum width of the auxiliary slit 54 may be shorter than the maximum width of the side slit 52, and the average width of the auxiliary slit 54 may be shorter. It may be shorter than the average width of the side slits 52.

The auxiliary slit 54 is a mark for aligning with the inguinal region in the front side region S1, and is easier to see than the side slit 52 provided in the inseam region S3. Therefore, even if the width of the auxiliary slit 54 is shorter than the width of the side slit 52, the function of the front marker portion can be easily exhibited. Further, since the width of the auxiliary slit 54 and the width of the side slit 52 are different, it becomes easier for the mounting assistant to distinguish between the auxiliary slit 54 and the side slit 52. The boundary between the auxiliary slit 54 and the side slit 52 can be easily grasped, the area to be arranged along the inguinal region can be easily grasped, and the absorbent article 10 can be easily aligned at an appropriate position.

Further, if the length of the auxiliary slit 54 in the width direction is too long, the length in the width direction of the portion where the absorption core 50 is deformed becomes long, and the length of the portion in which the absorption core 50 is arranged along the body becomes short. , There is a possibility that leakage may occur in the front side region S1. However, since the width of the auxiliary slit 54 is shorter than the width of the side slit 52, the length of the absorption core 50 in the front side region S1 in the width direction can be secured, and leakage in the front side region S1 can be suppressed. As shown in FIG. 6, the absorption core 50 can be fitted along the inguinal region of the wearer while suppressing leakage in the front side region S1.

The width of the auxiliary slit 54 is set to the side slit in order to suppress the discomfort when worn in the inseam area S3 and to obtain the effect of being able to fit along the wearer's inguinal region while suppressing leakage in the front side area S1. It may be 1/2 or less with respect to the width of 52. While securing the distance to move inward in the width direction by the side slit 52, it is possible to suppress the distance to move inward in the width direction in the front side region S1.

The central slit 55 may be located between the side slits 52 in the width direction W and may extend in the front-rear direction L. The central slit 55 may be separated from the side slit 52 in the width direction and may be separated from the auxiliary slit 54 in the width direction. At least a part of the central slit 55 may be arranged in the inseam region S3. The front end edge 55F of the central slit 55 may be arranged in the inseam area S3, and the rear end edge 55R of the central slit 55 may be arranged in the rear side area S2. The central slit 55 may be biased to the rear side of the side slit 52, and the front end edge of the center slit 55 may be located on the rear side of the front end edge 52F of the side slit 52. The central slit 55 may extend at least in the front-rear direction L, may be along the front-rear direction L, or may have a portion inclined with respect to the front-rear direction L.

The central slit 55 makes it easier for the first region R1 to bend in the thickness direction T, and the length of the entire absorber in the width direction can be further shortened. More specifically, when a force is applied from the outside to the inside in the width direction at the time of wearing, the inner edge of the first region R1 is on the skin surface side starting from the outer edge (side slit 52) of the first region R1. The absorption core 50 is easily deformed so as to face. Therefore, the length of the absorption core 50 in the width direction tends to be shorter. The absorption core 50 in the inseam region S3 is deformed so as to have a convex shape with the center in the width direction of the absorption core 50 as the apex, and the length of the entire absorption core 50 in the width direction can be further shortened.

Further, when the absorbent article 10 is used, the absorbent pad may be superposed on the skin surface side of the absorbent article 10. At this time, in the inseam region S3, the second region R2 of the absorption core 50 moves to the skin surface side T1 of the first region R1, so that the skin surface of the absorption core 50 is pushed up toward the wearer side and the absorption pad is pressed. Can be placed close to the skin surface. The absorbent pad can be fitted to the body to further suppress leakage. In the front side region S1, the fourth region R4 is deformed so as to rise toward the skin surface side with respect to the third region R3 with the auxiliary slit 54 as a base point. By arranging the absorption pad in the third region, the outer edge of the absorption pad can be held so as to be sandwiched by the fourth region. In this way, since the absorption core 50 is deformed along the inguinal region while holding the absorption pad, the absorption pad can be arranged along the region between the inguinal regions.

The maximum length of the third region R3 in the width direction W may be longer than the maximum length of the first region R1 in the width direction. The third region R3 sandwiched by the auxiliary slit 54 can secure a length in the width direction W more than the first region R1 sandwiched by the side slit 52, and the body can be covered by the absorption core 50 in a wide range. The length of the absorption core 50 in the front side region S1 in the width direction can be secured, and leakage in the front side region S1 can be suppressed.

The side slit 52 is located inside the outer edge 50S of the absorption core 50 in the width direction, and does not have to reach the outer edge 50S of the absorption core 50. According to this configuration, the absorbing material exists outside the side slit 52 in the width direction W. The absorbent material can retain the body fluid diffused by the side slit 52 and suppress lateral leakage.

The rear end edge 52R of the side slit 52 is located in the inseam region S3, and the side slit 52 does not have to reach the rear side region S2. According to this configuration, it is difficult for the region where the length of the absorber in the width direction W is shortened to reach the rear side region S2, and the absorption core 50 in the rear side region S2 can be applied to the body with a wide width to suppress leakage.

The auxiliary slit 54 is located inside the outer edge 50S of the absorption core 50 in the width direction, and does not have to reach the outer edge 50S of the absorption core 50. According to this configuration, the outer edge of the absorption core 50 can be applied in a plane to the body without being deformed by the auxiliary slit 54. Therefore, leakage in the front side region S1 can be further suppressed. Further, in the form in which the auxiliary slit 54 is configured by the slit, the absorbing material exists outside the auxiliary slit 54 in the width direction. The absorbent material can retain the body fluid diffused by the auxiliary slit 54 and suppress lateral leakage.

A leg elastic member 67 that contracts in the front-rear direction L may be provided outside the second region R2 in the width direction. The second region R2 is pulled up to the skin surface side T1 by the contraction of the leg circumference elastic member 67, and when a force is applied from the outside to the inside in the width direction when worn, the second region R2 becomes the skin surface side of the first region R1. It becomes easy to move inward in the width direction at T1. Therefore, the length of the absorption core 50 in the width direction tends to be shortened.

The absorption core 50 may have a constricted portion 51 having a length W in the width direction shorter than the maximum width of the absorption core 50. The region having a maximum width of 50M of the absorption core 50 is arranged so as to straddle the front side region S1 and the inseam region S3, and is arranged so as to straddle the posterior side region S2 and the inseam region S3. The constricted portion 51 of the absorption core 50 may be arranged in the inseam region S3. Since the length of the absorption core 50 in the width direction W of the inseam region S3 sandwiched between the wearer's crotch is short, the absorption core 50 can easily fit in the wearer's crotch, and a feeling of discomfort during wearing can be suppressed. The center 51CL of the constricted portion 51 in the anteroposterior direction L may be located in front of the center 10CL of the absorbent article 10 in the anteroposterior direction L. It is easy to obtain the effect of shortening the length of the absorber in the width direction W on the front side of the absorbent article 10.
