Abstract:
A manufacturing method for a stretchable composite sheet according to the present invention includes: a step for obtaining a laminate (8) configured such that a plurality of elastic members (4) are interposed between two sheet members (2), (3); and a fusion step for sandwiching the laminate (8) between an anvil roll (31) and a pressing surface (35a) of a fusion device (35) so as to form a fused section (5) at a site (51), on the laminate (8), where the elastic members (4) are not disposed. A plurality of recessed stripes (40) extending in a running direction (MD) of the laminate (8) are intermittently disposed in an orthogonal direction (CD) on the pressing surface (35a). When the laminate (8) is sandwiched between the anvil roll (31) and the pressing surface (35a) during the fusion step, the plurality of elastic members (4) in the laminate (8) are disposed in the recessed stripes (40).
