Abstract
The present invention is a solid electrolytic capacitor having a dielectric coating film, a solid electrolytic layer, and a cathode lead-out layer on a peripheral surface of an anode body in this order, in which the solid electrolytic layer is equipped with at least a first electrolytically polymerized layer and a second electrolytically polymerized layer formed by electrolytic polymerization of the same monomer, and the first electrolytically polymerized layer and the second electrolytically polymerized layer contain a different dopant. With this configuration, a solid electrolytic capacitor is provided that is superior in an ESR characteristic and also superior in heat resistance without deteriorating leakage current.
