Abstract
A solid electrolytic capacitor that includes a plurality of laminated units each including a valve action metal substrate including a porous layer on a surface thereof, a dielectric layer on a surface of the porous layer, and a solid electrolyte layer on the dielectric layer. A metal foil is between the laminated units. The units and the conductor layers are sealed with a coating resin. The valve action metal substrate has an anode section-side end surface directly connected to an anode outer electrode on the surface of the coating resin, and the metal foil is directly connected to a cathode outer electrode on the surface of the coating resin.
