There is provided a positive electrode for a nonaqueous electrolyte secondary battery, the positive electrode being capable of improving the charge-discharge cycle characteristics of the nonaqueous electrolyte secondary battery. A positive electrode 12 of a nonaqueous electrolyte secondary battery 1 contains positive electrode active material particles. The positive electrode active material particles contain a lithium-containing transition metal oxide. The lithium-containing transition metal oxide has a crystal structure that belongs to the space group P63mc. A compound of at least one selected from the group consisting of boron, zirconium, aluminum, magnesium, titanium, and a rare-earth element is attached to surfaces of the positive electrode active material particles.
