ABSTRACT:
By using the polarized electrode for electric double layer capacitor of the present invention, which is produced by mixing powdery activated carbon with a binder, and is characterized by the concentration of an organic compound being not more than 300 (ppm), the amount of organic compounds which remain in the pore of the powdery activated carbon decrease, and a possibility of forming the electric double layer by adsorption of electrolytic ion can be prevented. Thereby, an electric double layer is sufficiently formed inside the pore of the powdery activated carbon, and the diffusion resistance between the powdery activated carbon and the electrolyte becomes low. By constituting as such, an electric double layer capacitor with a large electrostatic capacity and a little internal resistance can be obtained.
