The present invention provides an underpants-type disposable diaper that has pleats formed in an outer body, which vertically and straightly extend, is excellent in appearance and air permeability, and is excellent in drawing preventing performance of a resilient and elastic member. The above-mentioned object is solved by a method for producing an underpants-type disposable diaper including, in forming stretchable regions, applying an adhesive to both an external surface of an inside layer and an internal surface of an outside layer in the same vertical striped pattern intermittent in an MD direction while transporting the inside layer and the outside layer, and then, fixing resilient and elastic members to the inside layer and the outside layer by bonding the inside layer and the outside layer to each other such that a position of the adhesive on the inside layer in the MD direction and a position of the adhesive on the outside layer in the MD direction are made to match with each other and sandwiching the resilient and elastic members between the inside layer and the outside layer continuously along the MD direction.

Stretchable structure with striped adhesive, method for producing, and absorbent article comprising the stretchable structure

Provided is a method for manufacturing a stretchable elastic member excellent in appearance and reduced in manufacturing cost by applying a first adhesive to an inner surface of a sheet at one side at predetermined intervals, applying a second adhesive to elongated resilient and elastic members at predetermined intervals, forming first application regions in which the first adhesive is applied and first non-application regions between the first application regions and the adjacent first application regions, forming second application regions in which the second adhesive is applied over a large number of the first application regions and second non-application regions between the second application regions and the adjacent second application regions, fixedly installing, on an inner surface of the sheet at the one side, the elongated resilient and elastic members and a sheet at the other side at the outer side of the elongated resilient and elastic members, and cutting the elongated resilient and elastic members in sections in which the first non-application regions and the second application regions oppose each other when seen from the above.
