A positive electrode active material includes: a lithium transition metal oxide which is in the form of a single particle and divided into a surface part and a core; and a coating part which is formed on the surface part and contains cobalt. The cobalt and nickel are contained in an amount satisfying a Co/Ni value (mol/mol) of 0.1 to 0.8 based on the entirety of the surface part and the coating part. A method for producing the positive electrode active material is also provided.
