  "textContent": "A positive electrode active material for a nonaqueous electrolyte secondary battery contains a first lithium-metal composite oxide represented by General Formula: LiNiCoMnMOand containing a secondary particle formed of a plurality of flocculated primary particles and either one or both of a first compound containing lithium and boron and a second compound containing lithium and tungsten. Either one or both of the following characteristics (1) and (2) are satisfied: (1) the first compound covers surfaces of the primary particles, and a boron content is at least 0.01% by mass and up to 0.5% by mass relative to the entire positive electrode active material; and (2) the second compound covers the surfaces of the primary particles, and a tungsten content is at least 0.01% by mass and up to 1.0% by mass relative to the entire positive electrode active material.",
