An absorbent article comprising a liquid-permeable top sheet, a back sheet, an absorber interposed therebetween, and three-dimensional gathers disposed along the longitudinal direction on either side on the use surface side of the absorbent article, wherein the three-dimensional gathers are disposed so as to form a pair of three-dimensional gathers (BS 1) on either side on a front side in a predetermined area containing the body fluid excretion portion in the longitudinal direction and so as to form a pair of three-dimensional gathers (BS 2) on either side on a back side in a buttock side portion, wherein the three-dimensional gathers are each made of a sheet folded in four, in a folded state, so that the sheet extending from the lateral side of the absorbent article toward the center side direction is folded back at a first folding portion toward the lateral side on a central side position, is folded back at a second folding portion toward the center side direction on a lateral side position subsequent to the first folding portion, and is folded back at a third folding portion toward the lateral side on a central side position subsequent to the second folding portion so that a first folding back surface, a second folding back surface, a third folding back surface, and a fourth folding back surface are formed in this order from a lower layer side of the absorbent article and so that the second folding portion is positioned on an outer side than an outward side end of the fourth folding back surface, wherein, in the predetermined area in the longitudinal direction of the absorbent article containing the body fluid excretion portion, the second folding back surfaces of the three-dimensional gathers (BS 1) are bonded to the use surface side of the absorbent article on the outer side than the outward side end of the fourth folding back surface, facing surfaces of the second folding back surfaces and the third folding back surfaces and facing surfaces of the third folding back surfaces and the fourth folding back surfaces are non-bonded, the three-dimensional gathers (BS 1) each have a side standing portion that stands from the side edge portion of the absorber or proximity thereof and a skin contacting portion having a predetermined width (L 1) and formed sequentially from an end of the side standing portion so as to be approximately horizontal with respect to the surface of the absorbent article or so as to incline toward the center side, and the three-dimensional gathers (BS 1) stand in a state in that the side standing portion is positioned on the outer side than the outward side end of the skin contacting portion, and wherein in the buttock side portion of the absorbent article, the first folding back surfaces and the second folding back surfaces of the three-dimensional gathers (BS 2) are not bonded to each other, the second folding back surfaces and the third folding back surfaces are bonded to each other, the third folding back surfaces and the fourth folding back surfaces are bonded to each other, and laminated layer portions of the second to fourth folding back surfaces (36,37,38) of the three-dimensional gathers (BS 2) stand linearly in an oblique manner toward the outer side direction using the first folding portion as a standing base point. the second folding back surfaces of the three-dimensional gathers (BS 1) are bonded to the use surface side of the absorbent article on the outer side than the outward side end of the fourth folding back surface, facing surfaces of the second folding back surfaces and the third folding back surfaces and facing surfaces of the third folding back surfaces and the fourth folding back surfaces are non-bonded, the three-dimensional gathers (BS 1) each have a side standing portion that stands from the side edge portion of the absorber or proximity thereof and a skin contacting portion having a predetermined width (L 1) and formed sequentially from an end of the side standing portion so as to be approximately horizontal with respect to the surface of the absorbent article or so as to incline toward the center side, and the three-dimensional gathers (BS 1) stand in a state in that the side standing portion is positioned on the outer side than the outward side end of the skin contacting portion, and the first folding back surfaces and the second folding back surfaces of the three-dimensional gathers (BS 2) are not bonded to each other, the second folding back surfaces and the third folding back surfaces are bonded to each other, the third folding back surfaces and the fourth folding back surfaces are bonded to each other, and laminated layer portions of the second to fourth folding back surfaces (36,37,38) of the three-dimensional gathers (BS 2) stand linearly in an oblique manner toward the outer side direction using the first folding portion as a standing base point.
