PURPOSE:To provide a capacitor high in withstand voltage and low in inner resistance by a method wherein a conductive electrode is formed on polarizing electrodes comprising an active carbon fiber and a water soluble binder while a pair of polarizing electrodes are arranged through the intermediary of a separator so as to be impregnated with an electrolyte. CONSTITUTION:The title dual layer capacitor is composed of polarizing electrodes comprising either one out of an active carbon fiber-made fabric, a non-woven fabric, a felt, a filter paper and a water soluble binder as well as said capacitor comprising a conductive electrode, a separator and an electrolyte. Since a layer comprising a carboxy methyl cellulose(CMC) layer 2 or a layer comprising CMC and an active carbon, a conductivity donator is held by the polarizing electrodes mainly comprising the active carbon fiber 1, the polarizing electrodes in low electric resistance and high capacity can be manufactured. Accordingly, the title capacitor comprising the polarizing electrodes and an organic electrolyte becomes an excellent capacitor combining the low resistance equal to that of conventional water soluble solution base capacitor with the high withstand voltage of an organic base capacitor. Furthermore, the direct current resistance can be lowered notably thereby enabling the long term reliability of the capacitor to be enhanced. |
