PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery which can restrain peel-off of a positive active material due to deterioration of adhesion even after repetitive charge and discharge cycles, improve cycle characteristics by restraining unevenness in charge/discharge reaction resulting from a gradual shift of an electrolyte solution of a negative electrode side toward a positive electrode side, and restrain deterioration of load characteristics. SOLUTION: With the nonaqueous electrolyte secondary battery provided with a positive electrode having a conductive agent, a bonding agent and a positive active material, a negative electrode, and a nonaqueous electrolyte, the conductive agent in the above positive active material layer contains carbon black with an average particle diameter of 60 to 100 nm measured by SEM, and a specific surface area of 20 to 30 m2/g measured by BET method. |
