A method of manufacturing a pants-type diaper comprises: a step A of conveying a first continuous sheet W4B a step B of laminating a plurality of continuous elastic bodies W4FG on an inner side of the first continuous sheet W4B, laminating a second continuous sheet W4T, and bonding at least a part of the continuous elastic bodies W4FG and the second continuous sheet W4T a step C of cutting a part of continuous elastic bodies 4FG from an outer side of the second continuous sheet W4T or an outer side of the first continuous sheet W4B and a step D of disposing the absorbent body 3 so as to arrange the absorber 3AC in a predetermined region. In the step C, a part of the continuous elastic bodies that is not bonded to the first continuous sheet is cut in a region for forming the pants-type diaper, the region other than a predetermined region for arranging the absorber.
