PROBLEM TO BE SOLVED: To provide a high silica-containing zeolite having a novel crystal structure and useful as various structural members. SOLUTION: The chemical composition is [(Si36 - x.O72 ) .My ] (where M represents an alkali metal cation such as Na, K, Li, etc., and x is 0≤x≤3.0). , Y represents a range of 0 ≦ y ≦ 3.0), and has a micropore formed by a covalent bond between a Si atom and an O atom, and includes a 5-membered ring and an 8-membered ring of silicon. Porous zeolite having a specific crystal structure (atomic arrangement) and having a specific diffraction peak at 2θ in powder X-ray diffraction. The present invention provides a novel high silica zeolite having a novel crystal structure having a silicon 5-membered ring structure and an 8-membered ring structure, having a high silica content, and having pores of 0.31 nm or more in the structure. be able to.
