ABSTRACT:
A miniature solid electrolytic capacitor is provided, which is suitable for being disposed within an electrically insulating layer, and is connected to other component using an electrically conductive adhesive with a connection resistance at an anode low and with connection reliability improved. Specifically, the electrolytic capacitor includes a valve metal element for an anode10having a capacitor forming part10A and an electrode lead part10B, a dielectric oxide film11formed on the valve element, a solid electrolyte layer12formed on the dielectric oxide film11and a charge collecting element for a cathode13formed on the solid electrolyte layer12, wherein at least one through hole15is formed in the electrode lead part10B so as to expose a core10C of the valve metal element, and an exposed portion10D of the core is used for connecting portion.
