  "textContent": "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 LiNiCoMnMO (0≤x≤0.35, 0≤y≤0.35, 0≤z≤0.10, 0.95≤s≤1.30, and 0≤α≤0.2, and M represents at least one element selected from V, Mg, Mo, Nb, Ti, W, and Al) and containing secondary particles formed by agglomeration of primary particles, wherein at least part of the surface of the primary particles thereof is covered with a lithium boron compound, and the amount of redundant lithium hydroxide of the positive electrode active material measured with a neutralization titration is at least 0.003% by mass and up to 0.5% by mass relative to the total of the positive electrode active material.",
