The present invention provides a positive electrode active material capable of more sufficiently preventing deterioration in cycle characteristics even when the positive electrode active material has a coating based on a metal alkoxide on its surface. The present invention relates to a positive electrode active material for a battery including a positive electrode active material core material and a coating formed on a surface of the positive electrode active material core material, whereinthe coating is an organic-inorganic hybrid coating formed of a reactant including at least a first metal alkoxide containing no metal atom-carbon atom bond in one molecule and a second metal alkoxide containing two or more metal atom-carbon atom bonds in one molecule.
