The present invention is a manufacturing method for a stretch laminate (W) which stretches and contracts in a width direction (Y), upon which a plurality of linear elastic members (F) are disposed so as to extend in the width direction (Y) between a first sheet (S1) and a second sheet (S2) across a transport direction (X) of the sheets (S1 and S2), wherein the method is provided with a step in which: on the surface of a folded-back roll (8) which becomes of smaller diameter toward both ends from the center of the width direction (Y), a complex (W1) is transported while coming into tactile contact with the surface on the opposite side of the first sheet (S1) in the second sheet (S2) of the complex (W1), whereupon, by the central portion (Wc) of the complex (W1) shrinking in the width direction (Y) so as to accompany shrinking of the central portion (Fc) of the elastic member (F), the folded-back portions (Sf) of the first sheet (S1) are folded back so as to overlap both side edge portions (Se) of the second sheet (S2).
