The LiS may contain impurities including at least one of LiOH, LiO, LiHCO, and LiCO. In the firing step, it is preferable that a concentration of a hydrogen sulfide in the hydrogen sulfide-containing atmosphere is 50 volume % or more. It is preferable that the raw material further contains PSand LiX (X represents at least one type of elemental halogen), and the sulfide solid electrolyte has an argyrodite-type crystal structure.",
