摘要： PROBLEM TO BE SOLVED: To establish an analysis/evaluation method of factors lowering a cell performance or a production yield in a positive electrode active material for a secondary cell, and to improve a production yield or a cell performance of a nonaqueous electrolyte secondary cell based on the analysis/evaluation method. SOLUTION: A positive electrode active material for use in a nonaqueous electrolyte secondary cell comprises a powdery compound metal oxide (LiCoO 2 , LiNiO 2 , LiMn 2 O 4 or the like). After the powdery metal oxide is classified with a classification precision index κ of 0.7 or greater so as to obtain coarse powders having a classification ratio in a range of 0.1% to 5%, the powdery metal oxide having a ratio (B/A) of the content ratio B of an impurity metal element in the coarse powders to the content ratio A of the impurity metal element in the powders before the classification being such as 1.5 or less is used as a positive electrode active material. The content ratio of the impurity metal element is compared with respect to Ca, Mn, Fe, Ni, Cr, Cu, Zn and the like (exclusive of the metal element constituting the powdery metal oxide).
