Side seal parts (S) are provided with joined parts (40) which extend continuously along a vertical direction (X). Elastic members (80a, 80b), which extend in a horizontal direction (Y), are provided, in a stretched state with spaces therebetween in the vertical direction (X), to both an abdominal-side part (A) and a back-side part (B). In either the abdominal-side part (A) or the back-side part (B), elastic-member (80a, 80b) ends positioned closer to the side seal parts (S), from among the elastic-member (80a, 80b) ends, do not reach positions of the side seal parts (S), and terminate at positions further inward in the horizontal direction than the side seal parts, thereby forming areas (9b) not having elastic members provided therein. In the areas (9b) not having the elastic members provided therein, an adhesive agent (10b) is intermittently applied along the vertical direction (X), in positions along extension lines extending in the horizontal direction (Y) from positions where the elastic members (80a, 80b) are provided. The ends of the elastic members (80b) are fixed by the adhesive agent (10b).
