摘要：
A positive electrode active material used for a nonaqueous electrolyte secondary battery, includes a base portion, a dielectric, and a carbonate compound. The base portion is formed of a compound storing and releasing a charge carrier. The dielectric is disposed on at least a part of a surface of the base portion. The carbonate compound is disposed on at least a part of the surface of the base portion.
