This diaper (1A) is obtained by joining both edge sections (2a 2b) of an outer layer body (2) having an absorbent body (3) attached thereto and forming a pair of side sealing sections (4) as a result. The outer layer body (2) has a low function region (WT) exhibiting a reduced stretching/contracting function in the attachment section (7) with the absorbent body (3). The outside lateral sections of the low function region (WT) and the side sealing sections (4) have respectively a lateral section adhesion region (IT) and a side sealing section adhesion region (OT) formed therein which have an elastic member (24) attached between an outer layer sheet (22) and an inner layer sheet (23) via an adhesive (8). The amount of the adhesive (8) used in the lateral section adhesion region (IT) and the side sealing section adhesion region (OT) repeatedly alternates in the Y direction between larger and smaller amounts in a manner such that the amount of the adhesive (8) in sections (IP OP) in which the elastic member (24) is disposed is greater than the amount of the adhesive (8) in the intervals (IN ON) between adjacent elastic members (24).
