    摘要： A positive electrode active material for non-aqueous electrolyte secondary battery composed of a lithium nickel composite oxide having high capacity and superior heat stability, a production method that is suitable for its industrial production, and a non-aqueous electrolyte secondary battery having high safety. The positive electrode active material for non-aqueous electrolyte secondary battery includes a lithium nickel composite oxide having by the following general formula (1): LibNi1-aM1aO2  (1) (wherein M1 represents at least one kind of element selected from transition metal elements other than Ni, the second group elements and the thirteenth group elements; a satisfies 0.01≦a≦0.5; and b satisfies 0.85≦b≦1.05). The amount of lithium at the surface of the lithium nickel composite oxide is 0.10% by mass or lower. The positive electrode active material is obtained by water washing fired powder at a temperature range of 10 to 40° C., and then filtering and drying the same.
