Abstract
A diaper has an outer sheet and a crotch member which includes a pair of skin-contactable sheets spaced from each other in a transverse direction. Inner side edges of the respective skin-contactable sheets cooperate with respective second ends of front and rear waist members to define an opening. A plurality of crotch elastic members is attached to the inner side edges. Under the effect of these crotch elastic members, a length dimension of the skin-contactable sheets is substantially reduced. The inner side edges of the skin-contactable sheets are spaced from the outer sheet in a thickness direction to form a space between the skin-contactable sheets and the outer sheet. A liquid-absorbent structure is provided in the space and includes a fold formed by folding the structure along a folding line. A top of the fold is bonded to the inner side edges of the respective skin-contactable sheets.
