Abstract

A method for manufacturing an absorbent article that includes: a first sheet body that includes two first sheets and a first elastic string that is stretchable and contractible in a left-right direction; a second sheet body; and a first weld portion. The method includes: (a) placing the first elastic string in a stretched state where the first elastic string is stretched in the left-right direction between the first sheets disposed in a thickness direction intersecting the left-right direction; (b) causing the second sheet body to overlap with the first sheet body in the thickness direction; (c) releasing the stretched state to bring about a released state; and (d) welding one end portion of the first sheet body in the left-right direction and one end portion of the second sheet body in the left-right direction to each other, to form the first weld portion.
