Abstract:
[Problem] To reduce unnecessary deformation of a side seal region. [Solution] Exterior bodies 12F, 12B have, at a junction position 80 that crosses elastic members 15, 17 and extends in a longitudinal direction LD, a junction part of a first sheet 12S and a second sheet 12H disposed so as to be in intimate contact with at least both sides of the elastic members 15, 17 with respect to the longitudinal direction LD, and a fixation part 84 for fixing the elastic members 15, 17. A side seal region 12A includes the fixation part 84 that fixes the elastic members 15, 17 set away laterally from the edge on the center side with respect to the width direction WD, and a group of weld parts 70 at least partially included in a rectangular region RA measuring ± 1.5 mm in the longitudinal direction LD from the fixation part 84. When the group of weld parts 70 is viewed from the longitudinal direction LD, the dimension of non-welded parts 72 in the width direction WD is smaller than 1.5 mm, the longest diameter of the weld parts 70 is 0.5-2 mm, and the area ratio of the weld parts 70 in the side seal region 12A is 5-30%.
