Abstract
The problem of the present invention is to provide a sulfide solid electrolyte material having excellent ion conductivity. The present invention solves the problem by providing a sulfide solid electrolyte material comprising an M1 element (such as a Li element), an M2 element (such as a Ge element and a P element), and an S element; having a peak in a position of 2θ=29.58°±0.50° in an X-ray diffraction measurement using a CuKα line; and having an IB/IA value of less than 0.50 when a diffraction intensity at the peak of 2θ=29.58°±0.50° is represented by IA and a diffraction intensity at a peak of 2θ=27.33°±0.50° is represented by IB.
