Zusammenfassung:Provided is a sulfide solid electrolyte that can reduce the reaction resistance between an active material and the sulfide solid electrolyte. A sulfide solid electrolyte having a weight loss rate of 2.6% or more and 9.6% or less, the percentage of weight loss rate being measured by heating the sulfide solid from 25°C to 400°C at a heating rate of 10°C/min in thermogravimetry. It is preferable that this sulfide solid electrolyte contains elemental lithium (Li), elemental phosphorus (P), elemental sulfur (S), an elemental halogen (X), and elemental oxygen (O). Also, this sulfide solid electrolyte is favorably produced by mixing a sulfide solid electrolyte with a compound that contains water of crystallization.
