Summary:PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having high reliability by using a manufacturing method accurately detecting and exhausting micro-short-circuit defects of the nonaqueous electrolyte secondary battery without deteriorating battery characteristics. SOLUTION: After conducting the finishing charge discharge of the nonaqueous electrolyte secondary battery, the first time voltage is measured after the nonaqueous electrolyte secondary battery is stored at 40-70°C, the second time voltage is measured after the nonaqueous electrolyte secondary battery is stored at -20°C to 20°C, and the difference between the first time voltage and the second time voltage is measured.
