Positive electrode for non-aqueous electrolyte secondary battery, battery using the same, and method of manufacturing positive electrode for non-aqueous electrolyte secondary battery

A positive electrode (1) has a positive electrode current collector, and a positive electrode mixture layer formed on at least one surface of the positive electrode current collector. The positive electrode mixture layer contains a positive electrode active material, a water-based binder, and a conductive agent. The positive electrode active material includes a lithium-transition metal composite oxide having an erbium compound adhered to a surface of the lithium-transition metal composite oxide, and the water-based binder includes a latex rubber.
