<p>PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor, in which reduction in leakage current under voltage application and improvement in self-discharging characteristics can be made by using PVDC(polyvinylidene chloride) electrodes, that are manufactured by adding a binder composed of phenolic resin to the carbonized powder of PVDC resin, a carbon electrode, and to provide a method of manufacturing it. SOLUTION: This method of manufacturing the carbon electrode 1 for an electric double-layer capacitor comprises a step of firing, to solidify carbonized powder of PVDC resin and the binder composed of phenolic resin, and a step of heat-treating the solidified body. The ratio of the phenolic resin with respect to the solid body is 5-40 wt.%.</p> |
