The present invention is a half width (W) of the peak in the average particle diameter (D50) on a volume basis of the secondary particles is from 3.0 to 25.0 ㎛, the volume of the average particle diameter (D50) and the secondary particle based on the particle size distribution is W≤0.4 D50 × Ni? Co satisfying? it relates to a manganese-based compound powder particles, and at the same time dropping? neutralizing the solution with an alkaline solution containing a metal salt in the alkaline solution can be obtained by performing the precipitation reaction. Ni? Co? Manganese-based compound particles powder of the present invention, since the particle size is uniform, crystalline low differential-bonding and the primary particle size, is useful as a precursor of the positive electrode active material used in the non-aqueous electrolyte secondary battery.
