Summary:PURPOSE:To provide a gas separation membrane wherein both oxygen transmitting degree and oxygen selective separation properties are satisfactory even though they are contradictory properties, pin holes are hard to be formed even if the membrane is made thin, and the membrane withstands high pressure and has high mechanical strength and flexibility. CONSTITUTION:A gas separation membrane is a composition cured body by radiation wherein the composition consists of at least one kind of organo- siloxane compounds having an unsaturated bond curable by radiation, at least one kind of polyester compounds having an unsaturated bond curable by radiation, and at least one kind of polyether compounds having an unsaturated bond- containing group curable by radiation and benzene ring-containing group.
