<p>Disclosed is a gas separation membrane which exhibits excellent heat resistance, gas permeability, and separation selectivity, and which is imparted with flexibility capable of withstanding a bending test. Also disclosed are a gas separation membrane having few pinholes, and a manufacturing method for the same. The gas separation film can provide a superior method for separating a gas mixture, a gas separation module, and a gas separation device containing a gas separation module. The gas separation film, which is for separating at least one type of acid gas from a gas mixture comprising at least one type of acid gas and at least one type of non-acid gas, is characterised by having a separation-active membrane comprising: a compound having specific structure and having a boiling point or decomposition temperature of at least 200°C; and a cross-linked polymer which contains a dissociable group and a repeating unit derived from an alkylene glycol.</p> |
