  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. In Formula (I), R represents a group having a specific structure. R3 represents a specific substituent group. A1 to A3 represent a hydrogen atom or a specific substituent group, but all of A1 to A3 do not represent a hydrogen atom at the same time. In this case, at least one of R3, A1, A2, and A3 represents a specific polar group.

  本发明提供了一种气体分离膜，该膜包括由聚酰亚胺化合物形成的气体分离层，其中聚酰亚胺化合物包括由下式（I）表示的重复单元；还提供了一种气体分离组件、一种气体分离装置和一种使用该膜的气体分离方法。 式（I）中，R 代表具有特定结构的基团。R3 代表特定的取代基。A1 至 A3 代表氢原子或特定取代基，但所有 A1 至 A3 不同时代表氢原子。 在这种情况下，R3、A1、A2 和 A3 中至少有一个代表特定的极性基团。
