PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery with improved discharging capacity at the time of large-current discharging. SOLUTION: With the nonaqueous electrolyte secondary battery provided with an electrode group 3 having a cathode 4, an anode 6 and a separator 5 arranged between the cathode 4 and the anode 6, and nonaqueous electrolyte solution, a lubricant layer 15 characteristically exists at least at a part of an interface of at least either the cathode 4 or the anode 6 and the separator 5. |
