A pull-on absorbent article comprising: an outer cover including an outer sheet that constitutes an outer surface, an inner sheet that is arranged on an inner surface side of the outer sheet, and a plurality of thread-form elastic members that are arranged in a stretched state between the outer sheet and the inner sheet; and an absorbent assembly that is fixed to the inner sheet of the outer cover; and both lateral side edge portions of the outer cover’s front portion which is arranged on a front side of a wearer are bonded with respective lateral side edge portions of the outer cover’s rear portion which is arranged on a rear side of the wearer so as to form a pair of side seals, a waist opening, and a pair of leg openings; wherein: in a fixing part where the outer cover and the absorbent assembly are fixed, the outer cover has a weak-functioning region in which the plurality of elastic members are each divided into a plurality of pieces and the elastic members’ elastic function is reduced; in respective outer lateral sides of the weak-functioning region, lateral-side adhesion regions are formed in which the elastic members are fixed between the outer sheet and the inner sheet by an adhesive; in the vicinity of the respective side seals, side-seal adhesion regions are formed in which the elastic members are fixed between the outer sheet and the inner sheet by an adhesive; between the lateral-side adhesion region and the side-seal adhesion region, the elastic members are not fixed between the outer sheet and the inner sheet; and in each of the lateral-side adhesion regions and each of the side-seal adhesion regions, the basis weight of the adhesive in a section where the elastic member is arranged is higher than the basis weight of the adhesive in a section between adjacent elastic members, and sections having a high basis weight and sections having a low adhesive basis weight alternate repeatedly in a longitudinal direction of the pull-on absorbent article.
