A trunks-type disposable diaper is configured to prevent shrinkage in the width direction of an inner thigh contact portion and to prevent the wearing feeling and occurrence of a gap. A crossing position of a front around-leg elastic member and a back around-leg elastic member positioned closest to an edge of a leg opening is positioned at the same position in a width direction as a side edge of the narrowest portion of a narrower portion of an absorber or on the center side in the width direction, and a crotch portion does not have elastic members other than the front around-leg elastic member and the back around-leg elastic member.
