Claim:
1. A sulfide solid electrolyte material comprising: a Li element; a Ge element; a P element; and a S element, wherein the sulfide solid electrolyte material has a peak at a position of 2θ=29.58°±0.50° in X-ray diffraction measurement using a CuKα ray, the sulfide solid electrolyte material does not have a peak at a position of 2θ=27.33°±0.50° in X-ray diffraction measurement using a CuKα ray or in a case of the sulfide solid electrolyte material having a peak at the position of 2θ=27.33°±0.50°, when diffraction intensity at the peak of 2θ=29.58°±0.50° is regarded as I a part of the P element in a crystal phase having the peak at the position of 2θ=29.58°±0.50° is substituted with a B element.
