PROBLEM TO BE SOLVED: To improve fittability to the roots of legs when walking.SOLUTION: A trunks-type disposable diaper includes: a first elastic member 26 that is continuously extended from one-side side seal part 21 in a front side along an edge 29 of a leg opening toward a crotch part 28, traverses the crotch part 28 obliquely backward, and heads for a part along the other-side leg opening along an edge 29 of the other-side leg opening, to be attached to the other-side side seal part 21 in a rear side and a second elastic member 27 that is continuously extended from the other-side seal part 21 in the front side along the edge 29 of the leg opening toward he crotch part 28, traverses the crotch part 28 obliquely backward, and heads for a part along the other-side leg opening along the edge 29 of the other-side leg opening, to be attached to the one-side side seal part 21 in the rear side. The first elastic member 26 and the second elastic member 27 are so formed that the parts along the edges 29 of the leg openings pass leg cylinder parts 30 at least one of the front side and the rear side of an outer wrapper body 20.SELECTED DRAWING: Figure 11COPYRIGHT: (C)2018,JPO&INPIT【課題】歩行時の脚の付け根に対するフィット性を改善する。【解決手段】上記課題は、前側における一方側のサイドシール部21から脚開口の縁29に沿って股間部28に向かい、股間部28を斜め後方に向かい横切って他方側の脚開口に沿う部分に向かい、他方側の脚開口の縁29に沿って後側における他方側のサイドシール部21まで連続的に取り付けられた第1弾性部材26と、前側における他方側のサイドシール部21から脚開口の縁29に沿って股間部28に向かい、股間部28を斜め後方に向かい横切って他方側の脚開口に沿う部分に向かい、他方側の脚開口の縁29に沿って後側における一方側のサイドシール部21まで連続的に取り付けられた第2弾性部材27とを有し、第1弾性部材26及び第2弾性部材27は、外装体20の前側及び後側の少なくとも一方で脚開口の縁29に沿う部分が脚筒部30を通過することにより解決される。【選択図】図11
