PROBLEM TO BE SOLVED: To provide a lithium zeolite film suitable as a solid electrolyte.SOLUTION: A lithium zeolite film 110 is obtained by forming a tabular product in which a lithium zeolite film 110, preferably of the ABW type, of a film thickness of 0.1-5 μm with e.g. sapphire substrate 111 or an electrode material of a lithium ion battery, such as LiCoO2, as the substrate 111, and the lithium zeolite film 110 is obtained by a step of preparing raw materials and carrying out hydrothermal synthesis at a hydrothermal temperature of 90-200°C for a hydrothermal time of 15-180 h using a raw material sol. |
