Even when used after being exposed to the atmosphere, this positive electrode for use in a nonaqueous electrolyte secondary battery suppresses reduction in initial discharge voltage. This positive electrode for a nonaqueous electrolyte secondary battery includes a lithium-containing transition metal oxide configured from secondary particles which are aggregates of primary particles. A rare earth compound adheres to at least part of the surface of the secondary particles, and a compound containing lithium and boron adheres to at least part of the surface of the secondary particles and to at least part of the interface between the primary particles aggregated on the surface of the secondary particles.
