Abstract
Provided is a positive active material for a nonaqueous electrolyte secondary battery which contains a lithium transition metal composite oxide, the lithium transition metal composite oxide having an α-NaFeOstructure, containing Ni, Co and Mn as a transition metal (Me), and having an X-ray diffraction pattern attributable to a space group R3-, in which a ratio of the full width at half maximum of a diffraction peak of the (003) plane to the full width at half maximum of a diffraction peak of the (104) plane, (003)/(104) at a Miller index hkl in X-ray diffraction measurement using a CuKα ray is 0.810 to 0.865, and a crystallite size is 410 Å or more.
