- the size of the diaper main body 10 can be matched to the physique of the wearer P by adjusting the locking method.
- the base sheet 21 of the fastening tape 20 is folded back at the fixed end 22, and the joining area is set between the locking parts 24 adjacent to each other in the front-rear direction D.
- 25 is joined to the diaper main body 10 via a joining structure 26.
- a pair of breaking portions 27 that can break the base sheet 21 along the bonding region 25 are formed on both sides of the bonding region 25 in the front-rear direction D.
- the base sheet 21 is torn at the breaking part 27, and the first tape 20a is joined in the front-back direction D with the joining area 25 set between the locking parts 24 in between.
- the second tape 20b is divided into two parts. Further, at this time, the bonding region 25 remains bonded to the diaper main body 10 by the bonding structure 26. As a result, a gap S is created between the first tape 20a and the second tape 20b in the front-rear direction D by the amount of the joining area 25.
- the tape-type disposable diaper 1 of Example 1 is arranged between the base sheet 21 (the first tape 20a and the second tape 20b) divided at the position between the locking parts 24 adjacent to each other in the front-rear direction D. A gap S can be created.
- a gap S is created between the divided base sheet 21 (the first tape 20a and the second tape 20b), so that when the fastening tape 20 is cross-fastened, the base (fixed end 22) of the first tape 20a and the base (fixed end 22) of the second tape 20b are less likely to interfere with each other.
- the helper can easily perform the cross fixing, and the gap that occurs around the legs of the wearer P can be appropriately suppressed.
- the caregiver can tear the base sheet 21 from the tearing portion 27 at the same time as gripping the locking portion 24 and unfolding the fastening tape 20. Therefore, in the tape-type disposable diaper 1 of Example 1, after the fastening tape 20 adhered to the diaper body 10 with a temporary adhesive or the like is peeled off and expanded, the tape-type disposable diaper 1 breaks from the perforation provided in the base sheet. Compared to tape-type diapers, it is possible to reduce the burden on caregivers.
- the joining region 25 remains joined to the diaper main body 10 even when the first tape 20a and the second tape 20b are unfolded. Therefore, the entire joint area 25 (base sheet piece) left between the divided base sheet 21 (first tape 20a and second tape 20b) is fixed to the diaper main body 10, and the locking portion 24 It won't get in the way when you lock it.
