Beschreibung
Zusammenfassung:	A method for producing a sulfide solid electrolyte of the present invention includes: a step of mixing a lithium (Li) element source, a phosphorus (P) element source, and a sulfur (S) element source, thereby obtaining a raw material composition; a step of firing the raw material composition, thereby obtaining a sulfide; a step of milling a slurry containing a solvent having fluorine atoms and the sulfide; and a step of drying the slurry. The sulfide in the slurry preferably has a concentration of 3 to 40 mass%. The step of milling a slurry is preferably a step of dry milling the sulfide, and mixing the dry milled sulfide and the solvent, thereby preparing the slurry.
