Abstract: Provided is a zeolite membrane 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 CF4 by a permeance of CO2 to be 0.015 or less, and has fewer defects.

Abstract: There is disclosed a ceramic separation membrane. This ceramic separation membrane includes a porous substrate, and a separation layer formed on the substrate. The separation layer is a laminate having an outermost layer positioned on the most surface side, and a base layer positioned in a lower layer than the outermost layer and made of zeolite. The outermost layer is a layer made of a siliceous material containing 90 mol % or more of silica, an organic material-containing amorphous silica material having a Si—Cn—Si (wherein n is 1 or 2) bond and a Si/C ratio of 0.5 to 2, or a carbonaceous material containing 90 mass % or more of carbon. The outermost layer is different from the base layer.
