Abstract
In a solid electrolyte obtained by sintering a powder, high ionic conductivity and remarkably low moisture permeation applicable to a lithium ion secondary battery or a lithium primary battery are realized. A method for producing a solid electrolyte including the steps of preparing a green sheet containing a lithium ion conductive inorganic material powder; and firing the green sheet, wherein in the step of firing the green sheet, at least one surface of the green sheet is covered by a setter having a porosity of not more than 10% by volume, is disclosed.
