A method for producing a solid electrolyte comprising feeding a solid electrolyte raw material-containing liquid comprising: a solid electrolyte raw material comprising lithium, phosphorus, sulfur and chlorine; and a solvent, to a liquid or gas medium having a temperature higher than the boiling point of the solvent, thereby evaporating the solvent and reacting the solid electrolyte raw material to precipitate a solid electrolyte having an argyrodite-type crystal structure. |
