1. A method for producing a sulfide solid electrolyte having an argyrodite crystal structure, the method comprising:
mixing a raw material comprising elemental phosphorus at an integrated power of 0.5 kWh/kg or more; and
heat-treating a precursor obtained in the mixing at a temperature in a range of from 350 to 500° C.
