要約
(EN)

A process for production of a laminate in which creasing is suppressed. The process for production of a laminate of the invention comprise a coating step for coating a porous membrane 1 with a coating liquid, and a laminating step for moving the porous membrane 1 coated with the coating liquid along the circumferential surface of a feed roller 14, moving the porous membrane 1 coated with the coating liquid along the circumferential surface of a lamination roller 30 together with a supporting substrate 2, and laminating the porous membrane 1 coated with the coating liquid and the supporting substrate 2 to obtain a laminate 3a,

wherein assuming the radius of the feed roller 14 is R1 (cm), the radius of the lamination roller 30 is R2 (cm), the distance between the central axes of the feed roller 14 and the lamination roller 30 is L (cm), the thickness of the porous membrane 1 is T1 (cm), and the thickness of the supporting substrate 2 is T2 (cm), a condition represented by the following expression (1) is satisfied.
