(Function and effect)
According to the disposable diaper 1 according to the present embodiment, the abdomen crotch distance L11 from the crotch narrowest part 80 to the crotch abdomen elastic member 5F ′ is from the crotch narrowest part 80 to the crotch dorsal elastic member 5R ′. Since it is shorter than the dorsal crotch distance L12, adhesion to the body is enhanced on the ventral side of the crotch narrowest portion 80. Specifically, since the wearer's disposable diaper 1 is less likely to hang down, the wearer's close contact with the urethral opening located on the abdomen side of the crotch narrowest portion 80 can be improved. Can be suppressed.

  Thus, according to the disposable diaper 1 which concerns on this Embodiment, the leak of the urine which is excrement can be suppressed in the ventral side of the disposable diaper 1. FIG.

  Furthermore, in the disposable diaper 1 according to the present embodiment, the ventral side crotch distance L11 is shorter than the back side crotch distance L12. In other words, since the back crotch distance L12 is longer than the abdomen crotch distance L11, a region having low adhesion to the body can be formed wider on the back side than the crotch narrowest portion 80. As a result, since it is possible to suppress the adhesion of the wearer to the vicinity of the anus located on the back side of the crotch narrowest portion 80, a space is easily formed between the disposable diaper 1 and the wearer. Thereby, since the allowable amount of stool, which is excretion, can be increased, for example, even when stool is excreted in a large amount, leakage of stool can be suppressed.

  A distance L31 in the front-rear direction L from the crotch narrowest portion 80 to the front side joint portion 92 is shorter than a distance L32 in the front-rear direction L from the crotch narrowest portion 80 to the rear side joint portion 93.

  Here, the joining portion 90 has higher strength than the region where the exterior body 1B is not joined to the absorbent main body 1A because the exterior body 1B is joined to the absorbent main body 1A.

  In the disposable diaper 1 according to the present embodiment, the distance L31 from the crotch narrowest portion 80 to the front side joining portion 92 is shorter than the distance L32 from the crotch narrowest portion 80 to the rear side joining portion 93. The region where the exterior body 1B is not joined to the absorbent main body can be narrowed from the portion 80 toward the ventral side. Thereby, since a low intensity | strength area | region can be narrowed toward the stomach side from the crotch narrowest part 80, when a wearer wears, the force which pulls up the disposable diaper 1 becomes easy to be transmitted. Therefore, for example, even a wearer with a reduced grip strength, such as an elderly person, can easily increase the degree of adhesion at the urethral orifice located on the ventral side of the crotch narrowest portion 80 by pulling up the absorbent article. it can.

  Further, the width LB in the width direction W from the rear side joining portion 93 to the end portion 1B ′ outside the width direction W of the exterior body 1B is from the front side joining portion 92 to the end portion 1B ′ outside the width direction W of the exterior body 1B. Therefore, when the rear waistline region S2 of the disposable diaper 1 is pulled up, in the crotch region S3, the force on the back side from the crotch narrowest portion 80 is easily dispersed. Thereby, when the back waistline area | region S2 of the disposable diaper 1 is pulled up, possibility that a failure | damage will generate | occur | produce in the area | region ranging from the crotch narrowest part 80 to the back waistline area | region S2 can be suppressed.

  In such a disposable diaper 1, the crotch back elastic member 5R ′ located closest to the crotch narrowest portion 80 is a rear waistline edge portion 6, 6 that is an outer end in the width direction W of the rear waistline region S2 of the exterior body 1B. It is curving toward the crotch narrowest part 80 side toward the width direction W inner side from '. Specifically, the crotch dorsal elastic member 5R ′ is positioned on both outer sides in the width direction with respect to the linear portion 52 extending linearly in the width direction and from the inner side in the width direction toward the outer side in the width direction. And a curved curve portion 53 extending from the front side, which is the front side in the front-rear direction, to the rear side, which is the front side in the front-rear direction. The straight portion 52 is disposed along the waistline elastic member, and the curved portion 53 is disposed along the leg opening 9. Therefore, compared to the case where the crotch dorsal elastic member 5R 'is formed only with a straight line portion extending linearly in the width direction, it is difficult to form a gap along the bulge from the leg roll to the buttocks. Thereby, the adhesiveness in a wearer's buttocks can be improved.

  According to the disposable diaper 1, the exterior body 1B includes at least one exterior center sheet 100 continuous over the front waistline region S1, the crotch region S3, and the back waistline region S2. Here, for example, when the exterior body 1B is configured by joining sheets separated into the front waistline region S1, the crotch region S3, and the rear waistline region S2, the strength at the joint portion is likely to decrease. . In such a case, when the disposable diaper 1 is pulled up, it is easily broken at the joint portion of the outer package 1B. According to the disposable diaper 1 described above, the exterior body 1B includes the front waistline region S1 and the inseam because it includes at least one exterior center sheet 100 continuous across the front waistline region S1, the crotch region S3, and the rear waistline region S2. The strength is improved as compared with the case where the region S3 and the rear waistline region S2 are separated and handed. As a result, when the disposable diaper 1 is pulled up, the outer package 1B is not easily torn and the lifting force is easily transmitted.
