1. A sulfide solid electrolyte material comprising a Li element, a Ge element, a P element, a S element, and an X element (X is at least one of F, Cl, Br, and I),wherein the sulfide solid electrolyte material comprising a crystal phase A having a peak at a position of 2θ

  • =29.58°

    ±

    1.00°

    measured by X-ray diffractometry using CuKα

    ray,having a composition of y(LiX)·

    (100−

    y) (Li3.35Ge0.35P0.65S4) (y satisfies the relationship;

    0<

    y<

    20), andthe sulfide solid electrolyte material does not comprise a crystal phase B having a peak at a position of 2θ

    =25.20°

    ±

    1.00°

    measured by X-ray diffractometry using CuKα

    ray.
