摘要：
The object of the present invention is to provide a sulfide solid electrolyte material with favorable ion conductivity. The present invention attains the object by providing a sulfide solid electrolyte material comprising an M 1 element (such as a Li element), an M 2 element (such as a Ge element and a P element), a S element and an O element, and having a peak at a position of 2θ = 29.58° ± 0.50° in an X-ray diffraction measurement using a CuKα ray, characterized in that when a diffraction intensity at the peak of 2θ = 29.58° ± 0.50° is regarded as I A and a diffraction intensity at a peak of 2θ = 27.33° ± 0.50° is regarded as I B , a value of I B /I A is less than 0.50.
