Claim:
1. A positive electrode for a non-aqueous electrolyte secondary battery in which a ratio value of a battery area to a rated capacity is 89.8 cm 2 /Ah or more, the battery area being a projected area of the non-aqueous electrolyte secondary battery including a battery outer casing body and the rated capacity being 3 Ah or more, the positive electrode comprising: a positive electrode current collector; and a positive electrode active substance layer that is formed on a surface of the positive electrode current collector and has a positive electrode active substance containing a lithium nickel-based composite oxide and a spinel type lithium manganese composite oxide, wherein, when an average secondary particle diameter of the lithium nickel-based composite oxide is D50(A), a content ratio of the lithium nickel-based composite oxide in the positive electrode active substance layer is A [% by mass], the average secondary particle diameter of the spinel type lithium manganese composite oxide is D50(B), and a content ratio of the spinel type lithium manganese composite oxide in the positive electrode active substance layer is B [% by mass], the positive electrode satisfies the following
