Abstract

Provided is a crystalline sulfide solid electrolyte having a high ionic conductivity and being capable of realizing a reduction in raw material cost, which contains a lithium atom, a phosphorus atom, a sulfur atom, an oxygen atom, and a halogen atom, has diffraction peaks at 2θ = 20.3 ± 0.5° and 29.6 ± 0.6° in X-ray diffraction measurement using a CuKα line, has a peak attributable to PSO<3>3- observed at 39.6 ± 5.0 ppm in solid-state <31>P-NMR measurement, and has a composition represented by the following composition formula: (100 - y)(0.5)(Li<3+2z>P(S<1-x>O<x>)<4+z>) + (y)LiX (in which, x, y, and z satisfy 0.00060 ≤ x ≤ 0.15, 3.0 ≤ y <25.0, and -0.17 ≤ z ≤ 1.5, respectively, and X represents a halogen atom).
