A nonaqueous electrolyte secondary battery capable of achieving a high battery performance (e.g., high energy density and high power density) is provided. The nonaqueous electrolyte secondary battery is equipped with a positive electrode having a positive electrode current collector and a positive electrode active material layer that is formed on the positive electrode current collector and includes at least a positive electrode active material and a conductive material. The positive electrode active material includes a lithium-transition metal composite oxide. The conductive material includes a lithium phosphate compound coated, on at least part of the surface thereof, with a conductive carbon, and a proportion of the conductive material in the positive electrode active material layer is 10% by mass or less. |
