PROBLEM TO BE SOLVED: To provide an art of easily adjusting a stretching rate in a fixed state of respective elastic members.
SOLUTION: A plurality of elongate elastic members 2 are aligned in parallel and clamped between an inner sheet 1A and an outer sheet 1B with their stretched state in the longitudinal direction, the inner sheet 1A and the outer sheet 1B are ultrasonically welded near the width-directional both ends of the respective elastic members 2, and then tension applied to the elastic members 2 is released to expand the elastic members 2 by contraction. When the elastic members 2 are clamped and fixed between the weld portion 3 near the width-directional one end of the elastic members and the weld portion 3 near the width-directional other end, an interval 3d between the weld portions 3 in the width-directional both sides of one elastic members 2 is formed different from an interval 3d between the weld portions 3 in the width-directional both sides of the other elastic members 2.
