Three-dimensional gathers that have a body fluid excretion portion and a buttock side portion having different cross-sectional views and that fit to the body shape of each portion and have highly comfortable fitting feeling are formed by a pair of three-dimensional gathers disposed on either side. In the three-dimensional gather BS, a sheet extending from the lateral side to the center side direction is folded in four by folding the sheet at the first folding portion 32 folded back toward the lateral side on a central side position and at the second folding portion 33 and the third folding portion 34 in series to form the first folding back surface 35, the second folding back surface 36, the third folding back surface 37, and the fourth folding back surface 38 in this order from the lower layer side. In a predetermined range containing the body fluid excretion portion H in the longitudinal direction of the absorbent article, at least the third folding back surface 37 and the fourth folding back surface 38 stand so as to form an approximately dogleg-shaped cross section, and in the buttock side portion, from the second folding back surface 36 to the fourth folding back surface 38 are bonded to one another, and stand linearly in an oblique manner toward the outer side direction using the first folding portion as the standing base point.
