Abstract

Resilient and elastic members are sandwiched between a first sheet material and a second sheet material and overlapping areas of the first sheet material and the second sheet material are not joined together at CD direction both end portions but are joined together at an area between the both end portions, thereby to form a belt-like continuous elastic belt. The elastic belt is cut in the middle of a CD direction thereof between the resilient and elastic members at a joined position of the first sheet material and the second sheet material to form a pair of divided elastic belt. CD direction positions of these divided elastic belts are exchanged or the divided elastic belts are vertically reversed. A ventral side outer body and a dorsal side outer body are formed from the pair of divided elastic belts.
