ABSTRACT:
A miniature solid electrolytic capacitor is provided, which is suitable for being disposed within an electrically insulating layer, and is connected to a component using an electrically conductive adhesive with a connection resistance at an anode being low and with connection reliability being improved. Specifically, the electrolytic capacitor includes a valve metal element for an anode having a capacitor forming part and an electrode lead part, a dielectric oxide film formed on the valve element, a solid electrolyte layer formed on the dielectric oxide film and a charge collecting element for a cathode formed on the solid electrolyte layer, wherein at least one through hole is formed in the electrode lead part so as to expose a core of the valve metal element, and wherein an exposed portion of the core is used as a connecting portion.
