A method for manufacturing a worn article, comprising the steps of: conveying one continuous sheet W1 that is continuous in a conveyance direction X; arranging a plurality of continuous elastic members F3, which are continuous in the conveyance direction X of the continuous sheet W1, on the continuous sheet W1 while the continuous elastic members F3 are stretched; arranging a plurality of non-continuous sheets W2 of a predetermined length intermittently and successively in the conveyance direction X on the continuous sheet W1 so that the continuous elastic members F3 are sandwiched between the non-continuous sheets W2 and the continuous sheet W1; in an overlapping area α where the non-continuous sheets W2 overlap with the continuous sheet W1, attaching the continuous sheet W1 and the non-continuous sheets W2 to each other by welding the continuous sheet W1 and the non-continuous sheets W2 to each other in a predetermined pattern, thus producing a continuous laminate L; and in a non-overlapping area β where the non-continuous sheets W2 do not overlap with the continuous sheet W1, heating the continuous sheet W1 in the same pattern as the predetermined pattern.
