Abstract:
An object of the present invention is to provide a separation membrane having high permeability and selective removability of divalent/monovalent ions. The separation membrane of the present invention includes a supporting membrane and a separation functional layer formed on the supporting membrane, in which the separation functional layer contains a polymerized product of a polyfunctional amine with a polyfunctional acid halide, the polyfunctional amine contains a polyfunctional aliphatic amine as a main component, the separation functional layer has a hollow protuberant structure, and the separation functional layer has a relative surface area of 1.1-10.0.

Claim (Index 6):
The separation membrane according to  claim 5 , wherein, in the separation functional layer, amino groups and amide groups which are derived from the polyfunctional aliphatic amine and carboxy groups and amide groups which are derived from the polyfunctional acid halide are present in a ratio that satisfies the following expression (2).\n 0.8\u2264(number of moles of amino groups and amide groups derived from polyfunctional aliphatic amine)/(number of moles of carboxy groups and amide groups derived from polyfunctional acid halide)\u22641.2\u2003\u2003(2)
