The present invention is to reduce the organic acid contained in the nonaqueous electrolyte secondary battery. When manufacturing the external film battery (1), nonaqueous electrolyte is injected to the exterior (5) of the external film battery (1) of electrode containing the electrode active material and binder, as well as organic acid. Then, the battery is filled until the voltage where organic acid is dissolved. The gas generated from the dissolution is discharged from the cutting part (6) of the exterior (5). |
