Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery endowed with both high battery capacity and charge and discharge cycle characteristics. SOLUTION: The nonaqueous electrolyte battery is produced by using a positive electrode active material wherein at least one kind of a metal element M1 different from a primary transition metal element A exists on at least a part of the surface of lithium-containing transition metal oxide including the primary transition metal element A and a compound of a metal element M2 different from the metal element M1 is adhered to at least a part of the surface of lithium-containing transition metal oxide including the primary transition metal element A or a compound of the metal element M2 different from the metal element M1 exists in the vicinity of the lithium-containing transition metal oxide. It is preferable that a whole composition of the positive electrode active material has a relationship of 0.001
