Summary: | Provided is a cathode active material that is for a non-aqueous electrolyte secondary battery able to achieve high electrode density and that obtains high output characteristics and battery capacity when used in a battery cathode, and provided is a non-aqueous electrolyte secondary battery that obtains a high output at a high capacity by using the cathode active material. A lithium-manganese-cobalt complex oxide is prepared comprising plate-shaped secondary particles aggregated by means of the plate surfaces of a plurality of plate-shaped primary particles overlapping, the shape resulting from projecting in a direction perpendicular to the plate surface of the plate-shaped primary particles is a sphere, an ellipse, an oval, or the planar projection of a blocky object, the aspect ratio of the secondary particles is 3-20, and the volume average particle size (Mv) according to a laser diffraction scattering method measurement is 4-20 micrometers.
