Patent abstract
A method of producing a separation membrane includes a seed crystal adhesion step of adhering zeolite seed crystals to a porous support formed of stainless steel to obtain a seed crystal-bearing support and a separation layer formation step of forming a porous separation layer formed of a zeolite on the seed crystal-bearing support. The stainless steel has a contact angle with water of 90° or more. The seed crystal adhesion step includes bringing the zeolite seed crystals and a solvent having a contact angle with the stainless steel of 30° or less into contact with the porous support.
