PURPOSE:To obtain a capacitor which is easy in manufacturing and favorable in properties by using a carbon porous substance, wherein a phenol resin forming substance is carbonized and activated and the density and specific surface area are specified, as a polarizable electrode. CONSTITUTION:Phenol resin is foamed and set, and is baked in nonoxidizing atmosphere for carbonization. Next, the carbide of porous substance is activated at a specified temperature in oxidizing gas so as to obtain a carbon porous substance. The density of this porous substance is made 0.05-0.7g/cm<3> or more, and the specific surface are 500m<2>/g or more. And an Al collecting electrode layer 2 is flame-coated by plasma at one side of the carbon porous substance 1, and this is impregnated with electrolyte, and a pair of porous substances 1 are piled up with a separator 5 between so as to constitute a polarizable electrode, which is housed by calking then the case 3a and 3b on the electrode sides through packings 4. Hereby, a small-sized and large capacity of capacitor can be obtained easily. |
