PROBLEM TO BE SOLVED: To provide a composite separation membrane with excellent heat resistance and durability, easy in film formation, thin in the film thickness, having a high permeability, and hardly swelling even in a hydrocarbon-containing atmosphere. SOLUTION: Provided is the composite separation membrane including an inorganic porous support body and an organic polymer membrane disposed in the fine holes of the inorganic porous support body. The thickness of the organic polymer membrane is 0.1-10 μm, and at least a part of the inorganic porous support body is exposed on the surface of the composite separation membrane.
