摘要：The invention has an object to reduce the impedance and to improve theresponsiveness at high frequencies in an electrolytic capacitor having an conductingpolymer layer as the cathode. A cathode collector is directly joined with the surface of

the dielectric of a valvular metal porous body for anode using a conducting polymerlayer but not through various binding layers (for example, a carbon layer and a silverlayer) thereby reducing the impedance. A cathode collector is disposed adjacent andopposite to a porous valvular metal foil for anode. This structure ensures that thecollecting area is enlarged. In this case, a cathode collector may be directly joined withthe surface of the dielectric of a valvular metal porous body for anode using anconducting polymer layer but not through various binding layers thereby reducing thetotal impedance.
