    摘要： There is provided a solid electrolytic capacitor including an anode body formed of a valve-action metal with a dielectric oxide coating layer formed on its surface, a cathode body, and an electroconductive polymer layer disposed between the anode body and the cathode body. The electroconductive polymer layer contains a softener for softening the electroconductive polymer layer, so that a solid electrolytic capacitor is provided that has small variations in characteristics, a lower equivalent series resistance (ESR), and an excellent high frequency property. In addition, when the anode and cathode of a solid electrolytic capacitor including an electroconductive polymer as a solid electrolyte are joined to each other, a lower ESR can be obtained under a lower pressure, and the electroconductive polymer layer can be prevented from being peeled off.

    摘要： The invention has an object to reduce the impedance and to improve the responsiveness at high frequencies in an electrolytic capacitor having an conducting polymer layer as the cathode. A cathode current collector is directly joined with the surface of the dielectric of a valvular metal porous body for anode using an conducting polymer layer but not through various binding layers (for example, a carbon layer and a silver layer) thereby reducing the impedance. A cathode current collector is disposed adjacent and opposite to a porous valvular metal foil for anode. This structure ensures that the collecting area is enlarged. In this case, a cathode current collector may be directly joined with the surface of the dielectric of a valvular metal porous body for anode using an conducting polymer layer but not through various binding layers thereby reducing the total impedance.

    摘要： A solid electrolytic capacitor includes a capacitor element having an anode of a valve action metal, an oxide film layer formed on the surface of the anode, a solid electrolytic layer formed on the oxide film layer and a cathode electrically connected to the solid electrolytic layer, and also a packaging resin formed to cover the capacitor element. An intermediate layer to relieve stress is arranged in at least one part of the interface between the cathode and the packaging resin. The intermediate layer is deformed and/or peels to relieve stress caused by heat applied while mounting the capacitor element on a substrate.

    摘要： Anodic valve metal foils, roughened and provided with dielectric layers, and collector metal foils (metal foils for collector) are laminated alternately to cross with cathodic electroconductive polymer layers therebetween. Anodic terminals and cathodic terminals are connected with the respective ends of the metal foils. For the anodic valve metal foils, an aluminum foil whose internal is an unroughened bulk metal layer is used. The collector metal foil is selected from the group consisting of an Al foil similar to the anodic valve metal foil, an Ni foil, a Cu foil, and an aluminum foil including carbon. As a result, a four-terminal capacitor to provide high capacitance, low impedance, high current-carrying capacity and less heat generation, as well as low ESR and low ESL, is obtained.
