| Zusammenfassung: | The gas separation membrane element contains a gas separation membrane, and a sealing portion for preventing mixture of a source gas and a specific gas permeated through a gas separation membrane. The gas separation membrane has a first porous layer including a porous membrane, and a hydrophilic resin composition layer disposed on the first porous layer. The sealing portion is a region in which a cured material of a sealant penetrates in at least the first porous layer in the gas separation membrane, and a thermal expansion coefficient A of the sealing portion and a thermal expansion coefficient B of a material forming the first porous layer satisfy a relation (I):0.35≤A/B≤1.0 |
