PROBLEM TO BE SOLVED: To provide an electrical double-layer capacitor that is hard to be degraded under a high temperature atmosphere.SOLUTION: An electrical double-layer capacitor 1 includes a positive electrode 12, a negative electrode 11, an exterior body 10, and an electrolyte. The positive electrode 12 has a positive-electrode side collector electrode 12a and a positive-electrode side polarizable electrode 12b. The positive-electrode side polarizable electrode 12b is provided on the positive-electrode side collector electrode 12a. The negative electrode 11 has a negative-electrode side collector electrode 11a and a negative-electrode side polarizable electrode 11b. The negative-electrode side polarizable electrode 11b is provided on the negative-electrode side collector electrode 11a. The negative electrode 11 faces the positive electrode 12. The exterior body 10 houses the positive electrode 12 and the negative electrode 11. The electrode capacitance of the negative-electrode side polarizable electrode 11b is larger than that of the positive-electrode side polarizable electrode 12b. |
