NOVELTY - A positive electrode includes a positive electrode electrical power collector (12), and positive electrode active material layer (15) formed on the surface of the positive electrode electrical power collector. The positive electrode active material layer has BET specific surface area of 1-3 m2/g, and comprises a positive electrode active material and a conductive support agent. The conductive support agent contains conductive support agent (A) and conductive support agent (B) having average particle diameter more than the conductive support agent (B).    USE - Positive electrode is used for nonaqueous electrolyte secondary battery (claimed) e.g. nonaqueous electrolyte lithium ion secondary battery for hybrid vehicle, electric vehicle and fuel cell electric vehicle.    ADVANTAGE - The positive electrode has high specific surface area, improves durability of the nonaqueous electrolyte secondary battery, suppresses reduction in discharge capacity in high output conditions, and reduces increase in battery temperature in overcharge state of the battery.    DETAILED DESCRIPTION - A positive electrode includes a positive electrode electrical power collector, and positive electrode active material layer formed on the surface of the positive electrode electrical power collector. The positive electrode active material layer has BET specific surface area of 1-3 m2/g, and comprises a positive electrode active material and a conductive support agent. The conductive support agent contains conductive support agent (A) and conductive support agent (B) having average particle diameter more than the conductive support agent (B). The content of conductive support agent (A) in the positive electrode active material layer is more than the content of conductive support agent (B).
