PROBLEM TO BE SOLVED: To provide a method for manufacturing a sulfide solid electrolyte, capable of manufacturing a sulfide solid electrolyte having ion conductive performance enhanced using a raw material including LiBr.SOLUTION: The method for manufacturing a sulfide solid electrolyte comprises: an input step of inputting a raw material for manufacturing a sulfide solid electrolyte mainly represented by a general formula (100-x)(0.75 LiS0.25PS)xLiBr (where, x is 0<x<100) into a vessel; an amorphization step of manufacturing an amorphous body formed by the amorphization of the raw material; and a sintering step of sintering the amorphous body. The reaction field temperature in the vessel is controlled so that x included in the general formula and a reaction field temperature y [°C] in the vessel in the amorphization step satisfy y<0.5x+1.48×10. |
