摘要： A method of producing a thin film of an inorganic solid electrolyte having a relatively high ionic conductance is provided. In the method, a thin film made of an inorganic solid electrolyte is formed, by a vapor deposition method, on a base member being heated. The thin film obtained through the heat treatment exhibits an ionic conductance higher than that of the thin film formed on the base member not being heated. The ionic conductance can also be increased through the steps of forming the thin film made of the inorganic solid electrolyte on the base member at room temperature or a temperature lower than 40° C. and then heating the thin film of the inorganic solid electrolyte.
