Abstract: Disclosed are a high silica zeolite having a novel crystal structure, a zeolite membrane and methods for producing them. The zeolite is represented by the chemical composition:[(Si36-xTy·O72)·Mz] (wherein M represents a cation of an alkali metal such as Li, Na, K and Rb; T represents Al, Ga, Fe and Ce as skeleton substituting elements; and x satisfies 0 ≤ x ≤ 3.0, y satisfies 0 ≤ y ≤ 1.0, and z satisfies 0 ≤ z ≤ 3.0), and has a micropore composed of a covalent bond of Si-O. The zeolite has a specific diffraction peak at 2θ in the powder x-ray diffraction pattern.
