Abstract
An active material of an embodiment for a nonaqueous electrolyte battery includes a complex. The complex includes a covering material including an M-O—C mixed body; and particles including at least one element of M. The particles are included in the covering material. The M includes at least one element selected from the group consisting of; Si, Sn, Al, and Ti. The particles including the at least one element of M include the at least one element of M or an alloy including the at least one element of M. The M-O—C mixed body includes at least three elements of M, O, and C. The M-O—C mixed body includes a point at which the following conditional expressions: 0.6≤M/O≤5 (molar ratio) and 0.002≤M/C≤0.1 (molar ratio) are simultaneously satisfied. The M-O—C mixed body includes the at least three elements of M, O, and C in a region excluding the particles including the at least one element of M when elementary composition analysis of the complex is performed by TEM-EDX with a beam diameter of 1 nm.
