Zusammenfassung:Provided is a sulfide solid electrolyte material which has a composition that does not contain Ge, while having a smaller Li content than conventional sulfide solid electrolyte materials, and which has both lithium ion conductivity and chemical stability at the same time. A sulfide solid electrolyte which has a crystal structure represented by composition formula (LiSn)(SiSn)(PSi)S(wherein α ≤ 0.67, β ≤ 0.33 and 0.43 < α + β (provided that 0.23 < α ≤ 0.4 when β = 0.2 and 0.13 < α ≤ 0.4 when β = 0.3 may be excluded)), or a crystal structure represented by composition formula LiSiPS(wherein 0.1 ≤ γ < 0.3).
