1. A sulfide solid electrolyte material comprising a Li element, a P element, and a S element and having peaks at positions of 2θ

  • =17.90±

    0.20, 29.0±

    0.50, and 29.75±

    0.25°

    in powder X-ray diffraction measurement using a Cu-Kα

    ray having an X-ray wavelength of 1.5418 Å

    , wherein assuming that a diffraction intensity of the peak at 2θ

    =17.90±

    0.20 is IA and a diffraction intensity of the peak at 2θ

    =18.50±

    0.20 is IB, a value of IB/IA is less than 0.50.
