    Abstract: PROBLEM TO BE SOLVED: To provide a gas separating zeolite membrane, a manufacturing method thereof, a gas separating zeolite membrane element and a gas separating zeolite membrane module, excellent even in durability, by highly selectively separating gas such as carbon dioxide, in a high aluminum including zeolite membrane being 10 or less in the atomic ratio of silicon (Si)/aluminum (Al) of a zeolite skeleton.SOLUTION: The manufacturing method of the gas separating zeolite membrane crushes a zeolite base material up to becoming an amorphous shape, and prepares an amorphous zeolite precursor, and then, coats a coating liquid of dispersing the amorphous zeolite precursor on a porous base body, and immerses an amorphous zeolite precursor coating porous base body in a zeolite membrane forming reaction solution, and the high aluminum including zeolite membrane being 10 or less in the atomic ratio of the silicon (Si)/the aluminum (Al) of the zeolite skeleton is formed on the porous base body by hydrothermal synthetic reaction. The produced zeolite membrane is desirably a faujasite (FAU) type zeolite membrane.
