A positive electrode active material according to one embodiment of the present invention contains secondary particles, each of which is formed by causing primary particles to aggregate, said primary particles being formed of a lithium-containing transition metal oxide that contains 80% by mole or more of nickel relative to the total number of moles of metal elements excluding lithium. This positive electrode active material additionally contains a rare earth compound that adheres to the surfaces of the secondary particles and a lithium compound that adheres to the surfaces of the primary particles within each secondary particle. The lithium compound contains lithium hydroxide.
