The two kinds of regions each have a rock-salt crystal structure. The inner layered rock-salt crystal structure and the two kinds of regions in the superficial portion are topotaxy. Since the crystal structure and the two kinds of regions are topotaxy, a change of the crystal structure of the positive electrode active material generated by charging and discharging can be effectively suppressed. In addition, since the outer coating layer in contact with an electrolyte is the compound of representative elements which is chemically stable, a secondary battery having excellent cycle characteristics can be obtained.SELECTED DRAWING: Figure 1
