A solid electrolyte having high ion conductivity and excellent battery performance is provided while simplifying the manufacturing process and reducing costs without going through a step of removing moisture such as a drying step. Specifically, a method for producing a sulfide solid electrolyte in which an alkali metal sulfide and a predetermined substance are reacted in the absence of a solvent or in a solvent other than water by mixing, stirring, pulverizing, or a combination thereof I will provide a. |
