PROBLEM TO BE SOLVED: To provide a gasoline separating membrane module for concentrating low-concentration gasoline vapor efficiently, and a vaporized fuel treating apparatus. SOLUTION: This gasoline separating membrane module 11 is constituted so that a layer 31 of the modified silicone obtained by modifying silicone with EPDM is formed on a gasoline separating membrane 11a, a purge pump 12 is arranged between an upstream chamber 11b divided by the membrane 11a and a canister and a pressure regulating valve 13 is connected to the chamber 11b so that the pressure of the chamber 11b is made higher than that of a downstream chamber 11c.
