    Abstract: The present invention provides a method for manufacturing a separation membrane suitable for transferring a separation functional layer and an intermediate layer from a release liner to a porous support member. The manufacturing method of the present invention is a method for manufacturing a separation membrane 10 including a separation functional layer 1, a porous support member 3, and an intermediate layer 2. The manufacturing method includes: forming the intermediate layer 2 on a first laminate 15 having a release liner 5 and the separation functional layer 1; bonding the intermediate layer 2 of a second laminate 16 having the release liner 5, the separation functional layer 1, and the intermediate layer 2 in this order to the porous support member 3 and thereby forming a third laminate 17; and removing the release liner 5 from the third laminate 17. In the manufacturing method, the intermediate layer 2 is formed in such a manner that a ratio R of an adhesive strength A2 (N/50 mm) between the intermediate layer 2 and the porous support member 3 with respect to an adhesive strength A1 (N/50 mm) between the release liner 5 and the separation functional layer 1 is 3.1 or more.
