PROBLEM TO BE SOLVED: To provide a polarity inversion equipment for a layered electric double layer capacitor which can prevent an excess voltage drop of the electric double layer capacitor cell in which the self-discharge is large in the polarity inversion and extend the lifetime. SOLUTION: The polarity inversion equipment for the layered electric double layer capacitor has features that a sharing voltage of the electric double layer capacitor C is measured by voltage sensors VS1-VS5 and relays CR1-CR3, XR1 and XR2, the minimum voltage value is monitored in the sharing voltage and a polarity inversion indication circuit for the polarity inversion of the electric double layer capacitor is used when the minimum voltage value falls below the predetermined value.
