An absorbent article comprising: wing-like flaps that are respectively disposed on both side edges of a main body in which an absorber is interposed between a liquid-permeable front sheet and a back sheet and are intended to be fixed to an undergarment by wrapping around a crotch portion of the undergarment when the article is worn; hip-holding flaps (W B) that are respectively disposed on both side edges of the main body at the posterior side than the wing-like flaps and that are intended to be fixed on the inner side of the undergarment at the buttock portion when the article is worn; a main body displacement-preventing adhesive layer on the back side of the absorber; wing displacement-preventing adhesive layers on the back sides of the wing-like flaps; hip displacement-preventing adhesive layers on the back sides of the hip-holding flaps (W B); and removable release paper sheets (30,31) covering the main body displacement-preventing adhesive layer, the wing displacement-preventing adhesive layers, and the hip displacement-preventing adhesive layers, wherein the release paper sheets (30,31) are constituted of a first release paper sheet covering all the main body displacement-preventing adhesive layer and the wing displacement-preventing adhesive layers in a unified manner and a pair of second release paper sheets respectively covering the hip displacement-preventing adhesive layers, wherein the hip-holding flaps (W B) are, together with the second release paper sheets, folded to the back side of the absorbent article, and the ends of the second release paper sheets protrude from the side edges of the hip-holding flaps (W B). wing-like flaps that are respectively disposed on both side edges of a main body in which an absorber is interposed between a liquid-permeable front sheet and a back sheet and are intended to be fixed to an undergarment by wrapping around a crotch portion of the undergarment when the article is worn; hip-holding flaps (W B) that are respectively disposed on both side edges of the main body at the posterior side than the wing-like flaps and that are intended to be fixed on the inner side of the undergarment at the buttock portion when the article is worn; a main body displacement-preventing adhesive layer on the back side of the absorber; wing displacement-preventing adhesive layers on the back sides of the wing-like flaps; hip displacement-preventing adhesive layers on the back sides of the hip-holding flaps (W B); and removable release paper sheets (30,31) covering the main body displacement-preventing adhesive layer, the wing displacement-preventing adhesive layers, and the hip displacement-preventing adhesive layers, wherein the release paper sheets (30,31) are constituted of a first release paper sheet covering all the main body displacement-preventing adhesive layer and the wing displacement-preventing adhesive layers in a unified manner and a pair of second release paper sheets respectively covering the hip displacement-preventing adhesive layers, wherein the hip-holding flaps (W B) are, together with the second release paper sheets, folded to the back side of the absorbent article, and the ends of the second release paper sheets protrude from the side edges of the hip-holding flaps (W B).
