Method of producing solid electrolyte member

Abstract

In production of a solid electrolyte member, the amount or kinds of sulfides used as raw materials are reduced. A method of producing a solid electrolyte member is a method of producing a solid electrolyte member based on sulfide, the method including: a preparation step (S10) of preparing an aggregate of starting materials, in which the starting materials include elemental sulfur, and a non-sulfide raw material that is at least one of an element as an elemental substance other than sulfur that constitutes the solid electrolyte member, and a compound of elements other than sulfur that constitute the solid electrolyte member; and a forming step (S12) of heating the aggregate of starting materials to form the solid electrolyte member. The non-sulfide raw material contains no elements other than elements except sulfur that constitute the solid electrolyte member, except inevitable impurities.
