The present invention provides nickel-cobalt-manganese composite hydroxide and a method for manufacturing same, the nickel-cobalt-manganese composite hydroxide as a precursor allowing a positive electrode active material having excellent battery characteristics and a high-density to be manufactured. The nickel-cobalt-manganese composite hydroxide is represented by a general formula: Ni 1-x-y-z Co x Mn y M z (OH) 2 (wherein 0 < x ‰¤ 1/3, 0 < y ‰¤ 1/3, 0 ‰¤ z ‰¤ 0.1, and M is at least one element selected from Mg, Al, Ca, Ti, V, Cr, Zr, Nb, Mo, and W) and serves as a precursor of a positive electrode active material for nonaqueous electrolyte secondary batteries; wherein the specific surface area measured by a nitrogen adsorption BET method is 1.0 to 10.0 m 2 /g, the carbon content measured by a high frequency combustion infrared absorption method is not more than 0.1 % by mass, and the half-value width of a (101) plane in X-ray diffraction is not more than 1.5°. |
