    摘要： A positive electrode for a nonaqueous electrolyte secondary battery that does not undergo a decrease in discharge capacity in low-temperature discharge during charge and discharge after the battery is left standing at high temperature in a charged state, for example. The positive electrode for a nonaqueous electrolyte secondary battery includes a positive electrode active material. The positive electrode active material includes a mixture of lithium nickel cobalt manganate and lithium cobaltate having a compound adhered to part of a surface thereof, the compound containing fluorine and at least one selected from zirconium, magnesium, titanium, aluminum, and a rare earth element; and a ratio of the lithium nickel cobalt manganate relative to a total amount of the positive electrode active material is 1% by mass or more and less than 70% by mass.
