Abstract
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.
