Abstract
In this diaper (A), both lateral side edge portions () of an outer cover () to which an absorbent assembly () is fixed are bonded together, so as to form a pair of side seals (). In a fixing part () where the outer cover () and the absorbent assembly () are fixed, the outer cover () has a weak-functioning region (WT) in which the elastic function is reduced. In each outer lateral side of the weak-functioning region (WT) and in each side seal (), a lateral-side adhesion region (IT) and a side-seal adhesion region (OT) are formed, respectively, in each of which elastic members () are fixed between an outer sheet () and an inner sheet () by an adhesive (). In each lateral-side adhesion region (IT) and each side-seal adhesion region (OT), the basis weight of the adhesive () in a section (IP, OP) where the elastic member () is arranged is higher than the basis weight of the adhesive () in a section (IN, ON) between a pair of adjacent elastic members (), and sections with high and low basis weights in adhesive () alternate repeatedly in the Y direction.
