description The present invention has an object to provide a positive electrode active material for a non-aqueous electrolyte secondary battery which not only suppresses gelation of a positive electrode mixed material paste upon producing the non-aqueous electrolyte secondary battery but also improves the stability thereof. Provided is the positive electrode active material represented by general formula LisNi1−x−y−zCoxMnyMzO2+α (0≤x≤0.35, 0≤y≤0.35, 0≤z≤0.10, 0.95
