Claim 0:
1. A negative electrode material comprising a reduced form of a solid electrolyte material,
wherein the solid electrolyte material is denoted by Formula (10) below,

Li3−3δ−aY1+δ−aMeaCl6-x-yBrxIy  Formula (10)

wherein Me represents at least one element selected from the group consisting of Zr, Hf, and Ti; and wherein
−1<δ<1,
0≤a<1.5,
0<(3−3δ−a),
0<(1+δ−a),
0≤x≤6,
0≤y≤6,
(x+y)≤6 are satisfied,
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, where X represents at least one element selected from the group consisting of F, Cl, Br, and I, and
θa is a value of the diffraction angle 2θ of the peak top of a peak derived from the solid electrolyte material and is a value closest to θb.
