Abstract: The present invention provides a separation membrane suitable for separating water from a liquid mixture containing an alcohol and water. The separation membrane of the present invention includes a metal organic framework. On the separation membrane, at least one of requirements (i) and (ii) below holds: (i) a ratio R1 of a number N2 of molecules satisfying a specified condition (b) with respect to a number N1 of molecules satisfying a specified condition (a) is less than 0.29; (ii) a ratio R2 of an adsorption amount of water adsorbed by the metal organic framework under water vapor at 25° C. and 3.2 kPa with respect to an adsorption amount of ethanol adsorbed by the metal organic framework under an ethanol atmosphere at 25° C. and 7.4 kPa is more than 4.0.
