Abstract
A solid electrolytic capacitor is provided that includes a capacitor element having a valve action metal base with a porous portion on a first main surface of a core portion, a dielectric layer disposed on a surface of the porous portion, a solid electrolyte layer disposed on the dielectric layer, and a conductor layer disposed on the solid electrolyte layer. Moreover, the capacitor includes a sealing layer that seals a first main surface of the capacitor element, a cathode outer electrode electrically connected to the conductor layer, and an anode outer electrode electrically connected to the valve action metal base. The sealing layer and the cathode outer electrode are disposed on the conductor layer and a cathode through-electrode extends through the sealing layer on the conductor layer. The conductor layer and the cathode outer electrode are connected to each other with the cathode through-electrode interposed therebetween.
