Abstract:
A spiral-wound type gas separation membrane element includes a central tube and a laminate wound around the central tube. Laminate includes at least one structure where a feed-side flow path member, a gas separation membrane, and a permeate-side flow path member are superimposed in this order. Permeate-side flow path member has a thickness of 400 μm to 1300 μm. Gas separation membrane is a membrane where a hydrophilic resin composition layer, a porous layer, and a permeate-side surface layer are superimposed in this order. Permeate-side surface layer faces Permeate-side flow path member and has a Young's modulus of 20 MPa to 400 MPa.
