摘要： A solid electrolytic capacitor capable of realizing miniaturization and large capacitance and obtaining the connection, in particular electric connection between the anodes, with low resistance and high reliability. A solid electrolytic capacitor includes: a laminate including a plurality of capacitor units in which a dielectric layer and a solid electrolytic layer are laminated in this order on a predetermined surface of an anode made of a valve metal; a sealing body for sealing the laminate; and an anodic conductive elastic body formed outside the sealing body and electrically connected to the anode. The anodes are adhered to each other via the conductive elastic body. In the solid electrolytic capacitor, a part of the anode is exposed to the outside of the sealing portion and the exposed portion is covered with a plating layer, and electrically connected to the anodic conductive elastic body via the covered exposed portion.

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.
