Li2S may contain impurities including at least one of LiOH, Li2O, LiHCO3, and Li2CO3. 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 P2S5 and LiX (X represents at least one type of elemental halogen), and the sulfide solid electrolyte has an argyrodite-type crystal structure.",
