Abstract

The present invention relates to a sulfide solid electrolyte comprising a crystal phase and a glass phase, wherein the glass phase includes a phase composed of sulfide-based glass containing Li, P, and S as constituent elements; the crystal phase includes a high-ion conductive crystal phase derived from the sulfide-based glass and an additional crystal phase; the composition of the high-ion conductive crystal phase and the composition of the phase composed of the sulfide-based glass satisfy 30-50 at% of Li, 5-15 at% of P, and 30-60 at% of S; and the additional crystal phase exhibits, in an XRD pattern obtained by powder X-ray diffraction measurement, two or more diffraction peaks different from diffraction peaks indicating the high ion conductive crystal phase within the range in which 2θ = 18.0°-22.5°.
