To provide a nonaqueous electrolyte battery with high capacity and excellent charge and discharge cycle characteristics by solving a problem that charge and discharge cycle characteristics are inferior in a nonaqueous electrolyte battery using silicon oxide for a negative electrode active material.

In this nonaqueous electrolyte battery using material expressed by general formula, SiOx(0sat the surface and xbat the center portion, a relation of xsand xbis expressed by xbs, when the the depth from the surface set to x=(xs+xb) in the material is za(nm), zais expressed by 5≤za≤50.
