Summary:A positive electrode active material for non-aqueous electrolyte secondary batteries that can achieve a high output characteristic and a high battery capacity when used in a positive electrode of a battery and that can achieve a high electrode density, and a non-aqueous electrolyte secondary battery that uses such a positive electrode active material and can achieve a high capacity and a high output. A lithium-manganese-cobalt composite oxide includes plate-shaped secondary particles each obtained by aggregation of a plurality of plate-shaped primary particles caused by overlapping of plate surfaces of the plate-shaped primary particles, wherein a shape of the primary particles is any one of a spherical, elliptical, oval, or a planar projected shape of a block-shaped object, 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 as measured by a laser diffraction scattering process.
