Abstract

A method for producing a protective-layer-covered gas separation membrane includes forming a gas separation membrane having a resin layer containing a compound having a siloxane bond and satisfying a particular condition by surface oxidation treatment of a resin layer precursor containing a siloxane bond; and providing a protective layer on the resin layer before winding. A protective-layer-covered gas separation membrane is produced by the method for producing a protective-layer-covered gas separation membrane. A gas separation membrane module and a gas separation apparatus are produced by the method for producing a protective-layer-covered gas separation membrane.
