Therefore, a sheet generated by folding back one of the sheets 34 and 35. Unevenness in the thickness direction can be eliminated and flattened. Therefore, the front panel 11 can be reliably attached to the crotch member 30 further.
  • the tip of the second leg-hole elastic member 60 is located in the narrow portion 73b of the third region 73, the contraction force of the second leg-hole elastic member 60 can be directly transmitted to the waist member 10. Therefore, in the wearing state, the second leg-hole elastic member 60 stands up with the side flap 38 upward with respect to the central region 37 by the contraction force, and the side edge of the side flap 38 is set on the wearer's buttocks. It can be pressed and the excrement can be prevented from leaking.
  • the leg-hole elastic members 50 and 60 are located outside the liquid absorption structure 40 in the horizontal direction X with respect to the horizontal virtual center line P.
  • the crotch both side edges 33 elasticized by 60 can adhere to the wearer's leg and prevent excrement from leaking.
  • the portions elasticated to the crotch side edges 33 by the first leg-hole elastic member 50 and the second leg-hole elastic member 60 are doubled, it is possible to reliably prevent excrement from leaking.
  • the liquid absorption structure 40 is disposed inside the folding line 39 in the lateral direction X with respect to the lateral virtual center line P, it does not become bulky in the crotch region 4.
  • the hot melt adhesive application region 70a differs from the application region 70 of the front panel 11 only in that only the wide portion 73a is provided and the narrow portion 73b is not provided. Further, the application area 70 a may have the same shape as the application area 70.
  • the first leg-hole elastic member 50 has been described as a series from the one end edge 31 side to the other end edge 32 side.
  • the first leg-hole elastic member 50 may be any member that prevents excrement from leaking from the crotch side edge 33 of the crotch member 30 at the portion where the waistline member 10 and the crotch member 30 overlap. Therefore, it suffices if the waistline member 10 and the crotch member 30 extend to the overlapping portion. In other words, as long as the first leg elastic member 50 extends to the portion where the waistline member 10 and the crotch member 30 overlap, as described above, the first leg elastic member 50 does not have to extend completely to the edges 31 and 32.
  • first leg-hole elastic member 50 may extend completely to the edges of both end edges 31 and 32. Further, the first leg-hole elastic member 50 does not need to be a series and may not exist in the crossing region 47. In other words, the first leg elastic member 50 may be configured by arranging a plurality of elastic members along the leg circumference.
