Summary:A positive electrode active material for a non-aqueous electrolyte secondary battery achieves high output characteristics and battery capacity, and allows a high electrode density to be achieved in the case of using the material for a positive electrode of a battery; and a non-aqueous electrolyte secondary battery uses the positive electrode active material, thereby achieving a high output with a high capacity. Prepared is a nickel composite hydroxide including plate-shaped secondary particles aggregated with overlaps between plate surfaces of multiple plate-shaped primary particles, where shapes projected from directions perpendicular to the plate surfaces of the plate-shaped primary particles are any plane projection shape of spherical, elliptical, oblong, and massive shapes, and the secondary particles have an aspect ratio of 3 to 20, and a volume average particle size (Mv) of 4 μm to 20 μm measured by a laser diffraction scattering method.
