The present invention provides an absorbent article improved so that bodily fluids can be absorbed by an absorbent structure from a skin-facing side of the absorbent structure and a non-skin-facing side thereof and thereby a liquid-absorbent core can be efficiently utilized. In a diaper 10, a crotch member 40 includes a pair of skin-contactable sheets 50 spaced from each other in a transverse direction X and an outer sheet 60. Inner side edges 53, 53 of the respective skin-contactable sheets cooperate with respective second ends 25, 35 of front and rear waist members to define an opening 41. A plurality of crotch elastic members 55 are attached to the inner side edges 53, 53 of the respective skin-contactable sheets and, under the effect of these crotch elastic members 55, a length dimension of the skin-contactable sheets is substantially reduced. The inner side edges 53 of the skin-contactable sheets are spaced from the outer sheet 60 in a thickness direction to form a space 42 between the skin-contactable sheets 50 and the outer sheet 60. Within this space 42, a liquid-absorbent structure 70 is provided. The liquid-absorbent structure 70 includes a fold 77 formed by folding the structure 70 along a folding line 76. A top of the fold 77 is bonded to the inner side edges 53 of the respective skin-contactable sheets 50.
