Provided are a gas separation membrane which includes a gas separation layer formed to include a polyimide compound and in which the polyimide compound includes a repeating unit represented by the following Formula (I), a gas separation module, a gas separation device, and a gas separation method using the same. n n n n n n n n n n In Formula (I), R represents a group having a specific structure. R 3 represents a specific substituent group. A 1 to A 3 represent a hydrogen atom or a specific substituent group, but all of A 1 to A 3 do not represent a hydrogen atom at the same time. n In this case, at least one of R 3 , A 1 , A 2 , and A 3 represents a specific polar group. |
