(JP2000012393-A)   NOVELTY - A solid electrolytic capacitor comprises a valve metal-made anode body on the surface of which are respectively formed a dielectric oxide layer, a composite conductive polymer layer made from a plurality of conductive polymer layers, a carbon layer and a silver layer.    USE - The capacitor can be used e.g. in batteries.    ADVANTAGE - The capacitor has high bonding and mechanical strength, conductivity, capacitance ratio and thermal stability and improved impedance, but low current leakage.
