Claim 1:
2. The negative electrode material according to claim 1,
wherein a peak top is present at the value of the diffraction angle 2θ within the range of greater than θa and less than or equal to θb in an X-ray diffraction pattern of the reduced form obtained by X-ray diffraction measurement in which the Cu-Kα ray is used as a radiation source,
θb is a value of the diffraction angle 2θ of the peak top of a peak reflecting the (220) face of LiX composed of Li and X, and
θa is a value of the diffraction angle 2θ of the peak top of a peak derived from the first solid electrolyte material, which is not reduced, and is a value closest to θb.
