PROBLEM TO BE SOLVED: To provide an output compensator of an electric double layer capacitor, capable of setting the capacity of the electric double layer capacitor by previously knowing aged deterioration in the capacitor and of enduring the extension of the compensation time and an overload immediately after the start of use because the electric double layer capacitor has an increase in internal resistance and reduction in the capacity due to aged deterioration. SOLUTION: This output compensator regularly calculates the compensation time based on the aged deterioration characteristics of the electric double layer capacitor 1 and the actual usage to set the compensation time for time. The compensation time regularly matches the rated capacity by taking the aged deterioration in the capacitor capacity and internal resistance into consideration and measuring the capacitor ambient temperature and the operating time. A data table is created and stored in an operation unit by previously calculating the compensation time to meet the rated capacity, thereby regularly retrieving the compensation time according to the actual operating state from the data table.
