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 3 a, wherein assuming the radius of the feed roller 14 is R 1 (cm), the radius of the lamination roller 30 is R 2 (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 T 1 (cm), and the thickness of the supporting substrate 2 is T 2 (cm), a condition represented by the following expression (1) is satisfied. <?in-line-formulae description="In-line Formulae" end="lead"?>R1+R2+T1+T2<=L<=R1+R2+100 (1) <?in-line-formulae description="In-line Formulae" end="tail"?> |
