<P>PROBLEM TO BE SOLVED: To provide a gas separation composite membrane, which achieves a high gas separation selectivity, while having a superior gas permeability, and further which attains a higher membrane formability, and to provide a method of manufacturing the same, a module using the same, and a separation apparatus. <P>SOLUTION: The gas separation composite membrane has a gas separation layer containing a crosslinked polyimide resin on an upper side of a supporting layer with the gas permeability. In the crosslinked polyimide resin, a polyimide compound has a structure cross-linked by a cation crosslinkable functional group derived from the molecule or another molecule. <P>COPYRIGHT: (C)2013,JPO&INPIT |
