There is provided a positive electrode for nonaqueous electrolyte secondary batteries in which a decrease in the initial discharge voltage can be suppressed even when a positive electrode exposed to the air is used. The positive electrode for a nonaqueous electrolyte secondary battery according to an aspect of the present invention contains a lithium transition metal oxide constituted by a secondary particle formed by aggregation of primary particles. A rare-earth compound adheres to at least part of a surface of the secondary particle, and a compound containing lithium and boron adheres to at least part of the surface of the secondary particle and at least part of an interface between primary particles aggregated at the surface of the secondary particle.
