The invention relates to a positive electrode for a nonaqueous electrolyte secondary battery and a nonaqueous electrolyte secondary battery. A positive electrode (11) for a nonaqueous electrolyte secondary battery according to an embodiment of the present disclosure includes a positive electrode current collector (30) mainly composed of aluminum (Al), a protective layer (31) disposed on the positive electrode current collector (30), and a positive electrode mixture layer (32) containing a lithium-containing transition metal oxide and disposed on the protective layer (31). The protective layer (31) has a thickness of 1 to 5 mu m and contains an electroconductive material and an inorganic compound having an oxidation power lower than that of the lithium-containing transition metal oxide.
