It is intended to provide a nonaqueous electrolyte battery that satisfies both of a large discharge capacity and a superior cycle life characteristic by developing a novel negative electrode material. A nonaqueous electrolyte battery uses a negative electrode active material that is a compound expressed by Formula (1): <?in-line-formulae description="In-line Formulae" end="lead"?>A<SUB>z</SUB>MX<SUB>y</SUB> (1)<?in-line-formulae description="In-line Formulae" end="tail"?> where A is at least one element selected from the alkali metals, M is at least one element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd, Os, Ir, Pt, and Mg, X is at least one element selected from the group consisting of B, N, Al, Si, P, Ga, Ge, As, In, Sn, Sb, Pb, and Bi, 0<=z<=20, and 0.2<=y<=6.
