    Abstract: A method for manufacturing a zeolite membrane with fewer defects; a zeolite membrane having oxygen eight-membered rings with fewer defects; and a method for evaluating a zeolite membrane having oxygen eight-membered rings which enables to evaluate defects are provided. The zeolite membrane is manufactured by: subjecting a porous body to heat treatment at 400°C or more in the presence of oxygen as pretreatment, before adhering zeolite seed crystals to a surface of the porous body; storing the porous body under an environment of humidity of 30% or more for 12 hours or more after the heat treatment; and subsequently adhering the zeolite seed crystals to the porous body. The zeolite membrane having oxygen eight-membered rings, which is manufactured by subjecting the porous body to the heat treatment, provides a value that is obtained by dividing a permeance of CF 4 by a permeance of CO 2 to be 0.015 or less, and has fewer defects.
