A solid electrolytic capacitor is provided, which can reduce impedance, particularly, the ESL and the ESR. In one embodiment, such a solid electrolytic capacitor comprises a foil-like valve metal substrate formed with an insulating oxide film on the surface thereof, a valve metal body whose one end portion region is bonded to one of two opposite end portion regions of the foil-like valve metal substrate, a conductive metal substrate whose one end portion region is bonded to the other end portion region of the foil-like valve metal substrate, a cathode electrode formed by sequentially laminating at least a solid high molecular polymer electrolyte layer and a conductive layer on the surface of the foil-like valve metal substrate, and a cathode lead electrode being drawn out from the cathode electrode in a direction perpendicular to one major surface of the foil-like valve metal substrate. |
