A membrane for gas separation includes a porous support layer and a separation layer. The separation layer comprises a mixture of one or more saccharide derivatives and one or more homopolymers. The saccharide derivative(s) may have a cyclic structure with five or six ring atoms, or a linear structure, or may include monosaccharide derivatives which are bound via glycoside bonds, and the number of monosaccharides bound in this manner may be 2 to 1,000. A membrane can be produced by preparing a homogeneous solution which comprises a saccharide derivative and a homopolymer in a solvent; and pouring the homogenous solution onto a support layer. The membrane may be used in a gas separation module the operation of which makes use of the membrane.
