Positive electrode plate for nonaqueous electrolyte secondary battery, nonaqueous electrolyte secondary battery, and method for manufacturing positive electrode plate for nonaqueous electrolyte secondary battery

And the proportion of the conductive material of the positive electrode plate for the non-aqueous electrolyte secondary battery is optimized. This lithium ion secondary battery is provided with a positive electrode plate, a negative electrode plate, a separator, and a non-aqueous electrolyte solution. The positive electrode plate is provided with a positive electrode current collector and a positive electrode mixture layer which is provided on the surface of the positive electrode current collector and which is composed of a positive electrode mixture containing a positive electrode active material and a conductive material. When the ratio of the conductive material in the positive electrode composite material is RC, the specific surface area of the conductive material is BC, the ratio of the positive electrode active material in the positive electrode composite material is RA, the specific surface area of the positive electrode active material is BA, and the total surface area ratio is RS, RS = (RC * BC)/(RA
