  A gas separation membrane includes a gas separation layer containing a polyimide compound, and the polyimide compound has a repeating unit represented by Formula (I). The gas separation module, the gas separation device, and the gas separation method are obtained by using the gas separation membrane, R a represents a specific tetravalent group, R b represents a trivalent group having a specific ring, X a represents a specific substituent, and X b represents a hydrogen atom or a substituent. A polyimide compound represented by Formula (I-b) or (I-c), R a represents a specific tetravalent group, R c represents a specific divalent group, A a , A b , A c , and X b represent a hydrogen atom or a substituent, and X c and X d represent a specific substituent.
