Abstract
An electronic apparatus has an electric load, an electrochemical capacitor, and an applying section. The electric capacitor includes a positive electrode, a negative electrode and an electrolyte placed between the positive electrode and the negative electrode and supplies electric power to the electric load. The applying section opens an electrical connection between the electrochemical capacitor and the electric load, and applies a minus potential to the positive electrode and a plus potential to the negative electrode.
