A method of producing a positive electrode active material includes a first step and a second step. In the first step, a mixture of a lithium compound and a transition-metal-containing compound containing a transition metal is calcined with a heater in an oxygen atmosphere at a calcination temperature of 750 to 1000° C. to obtain a lithium transition metal composite oxide. In the second step, microwave is applied to the lithium transition metal composite oxide while the lithium transition metal composite oxide, after the first step, has a temperature of 400° C. or more and less than the calcination temperature in the first step.
