Abstract
The present invention provides a titanosilicate separation membrane which can also be used for separating a mixed gas containing a molecule having a relatively small size, has high durability in a high temperature environment, and has a high permeation rate and a high selectivity for a mixed gas containing water vapor. A titanosilicate separation membrane has a CHA-type titanosilicate crystal structure formed on a porous support, wherein aluminum is not substantially contained in the backbone of the titanosilicate crystal structure, and the titanosilicate crystal structure is constituted by silicon, oxygen, and titanium.
