A lithium nickel composite oxide, having small inner resistance, large battery capacity and high thermal stability, can be used as a positive electrode active material for a non-aqueous electrolyte secondary battery. The positive electrode active material is composed of the lithium nickel composite oxide of LibNi1-aMaO2 (wherein M represents at least one element selected from a transition metal element other than Ni, the second group element and the thirteenth group element; a satisfies 0.01≦a≦0.5; and b satisfies 0.9≦b≦1.1). This is obtained by filtering and drying the fired powder after water washing, wherein it is dried at 90° C. or lower, till moisture is reduced to 1% or less by mass in drying, and then at 120° C., and under gas atmosphere where content of compound components containing carbon is 0.01% or less by volume, or under vacuum atmosphere.
