Abstract
A organic electrolytic capacitor comprising a positive electrode, a negative electrode and an aprotic organic solvent of a lithium salt as an electrolytic solution, wherein a positive electrode active material is capable of reversibly holding lithium ions and anions, a negative electrode active material is capable of reversibly holding lithium ions, the negative electrode active material has three times or more capacitance per unit weight as the positive electrode active material, the weight of the positive electrode active material is larger than the weight of the negative electrode active material, and the negative electrode is provided with lithium deposited thereon in advance. Ease of manufacture, high capacity and high withstanding voltage are achieved with this constitution.
