Abstract
There is provided a zeolite membrane which is thinner than a conventional membrane and which has improved permeability and a method for manufacturing the zeolite membrane. The method includes a surface layer forming step for forming a surface layer by attaching a low polar polymer on a first surface of a porous substrate to cover the surface, a filling step for filling a masking polymer into pores in the porous substrate from a surface different from the first surface of the porous substrate up to the surface layer by impregnating the porous substrate with the masking polymer and solidifying the masking polymer, and a surface layer removing step for removing the surface layer. After the surface layer removing step, a zeolite membrane is formed on the first surface of the porous substrate.
