FIG. 10 is a cross-sectional view of the main parts of the fastening belt portion 320 and the ventral side portion 311 in a state where the disposable diaper 300 is assembled.
The disposable diaper 300 according to the second modification is the same as that in the above embodiment except for the configuration of the fastening belt portion 320 and the abdominal side portion 311 described below, and thus the description thereof is omitted.

As shown in FIGS. 8 to 10, the disposable diaper 300 according to the second modified example is provided with two abdomen side fastening portions 32 a and 32 b so as to sandwich the belt main body portion 21 in the front-rear direction.
That is, as shown in FIG. 10, one abdomen side fastening part 32a and the body part fastening part 31 are arranged on the rear side with respect to the belt body part 21 of the fastening belt part 320, and the other stomach side The part fixing part 32 b is disposed on the front side with respect to the belt main body part 21.
The two ventral side fastening portions 32a and 32b are preferably arranged so as not to overlap each other in the radial direction of the annular member 330 (for example, the front-rear direction in FIG. 10). The thickness of the member 330 in the radial direction becomes too thick, and the wearer's wearing feeling wearing the paper diaper 300 can be prevented from being lowered.

Further, the ventral portion 311 is longer in the longitudinal direction X than in the above embodiment. That is, one abdomen side fastening part that is fastened to the abdomen side part securing part 11a of the abdomen side part 311 by increasing the length in the longitudinal direction X of the abdomen side part 311 by a predetermined length. The position of the longitudinal direction X of 32a can be adjusted. Thereby, in the wearing state of the paper diaper 300, the length of the crotch circumference from the back side to the abdomen side of the paper diaper 300 can be adjusted, so that it is possible to deal with wearers having different lengths around the crotch.
That is, by ensuring a sufficient length around the crotch, a wearer with a relatively short crotch length, i.e., a wearer with a small body, can relatively reduce the length around the crotch. Even long wearers, that is, wearers with large bodies can be accommodated.

Of the two ventral side fastening portions 32 a and 32 b, one ventral side fastening portion 32 a disposed on the rear side with respect to the belt main body portion 21 is the belt main body portion 21 in the ventral side portion 311.

Between the belt body 21 and the wearer's skin, the abdomen 311 is arranged while the center of the abdomen 311 is aligned with the center of the wearer's body. At this time, when the length of the wearer's abdomen in the vertical direction is shorter than the length in the longitudinal direction X of the abdomen 311, the tip side of the abdomen 311 protrudes from the upper end of the belt body 21. (See FIG. 8).
Then, after fixing one abdomen side fastening part 32a on the rear side of the belt body part 21 to the abdomen side part fastening part 11a of the abdomen side part 311, the belt body part 21 of the abdomen side part 311 The portion protruding from the upper end is folded back to the opposite side of the wearer's skin, and the folded portion of the abdomen side part to be secured 11a and the other abdomen side part to be secured 32b on the front side of the belt body part 21 are connected. Fasten (see FIGS. 9 and 10).

  Therefore, according to the disposable diaper 300 of the second modified example, the two abdomen side fastening portions 32a and 32b are provided on the annular member 330 so as to sandwich the belt main body 21 in the front and rear directions. The one abdomen side fastening part 32a disposed on the rear side can be fastened to the abdomen side part secured part 11a of the abdomen side part 311 and the other side on the front side with respect to the belt body part 21 The abdomen side fastening part 32b of the abdomen can be secured to the abdomen side part secured part 11a of the part of the abdomen side part 311 that is folded back on the side opposite to the wearer's skin above the belt body part 21. . Thereby, even if it is the paper diaper 300 to which the length of the longitudinal direction X of the abdominal side part 311 was lengthened so that it could respond | correspond to the wearer from which the length of the crotch circumference from the back side to the abdominal side differs, The feeling of wearing of the paper diaper 300 can be improved by fixing it at a predetermined position without leaving a portion protruding from the upper end of the belt main body portion 21 of the portion 311.
