It has been difficult to have a current blocking device reliably operate, while maintaining the high-rate characteristics of a nonaqueous electrolyte secondary battery. Consequently, this positive electrode for nonaqueous electrolyte secondary batteries, which is configured by forming a positive electrode mixture layer by coating a collector with a positive electrode mixture paste that contains a positive electrode active material, is configured such that: the positive electrode active material has particle diameters of 2 [mu]m or more but less than 7 [mu]m; the positive electrode mixture layer comprises a first mixture layer, wherein the maximum diameter of the pores formed between positive electrode active material particles is more than 1.0 [mu]m but 5.0 [mu]m or less, and a second mixture layer, wherein the maximum diameter of the pores is 1.0 [mu]m or less; the second mixture layer is arranged closer to the collector plate than the first mixture layer; and the ratio of the thickness of the first mixture layer to the thickness of the second mixture layer is more than 0.1 but 1.0 or less.
