Abstract
A solid electrolytic capacitor, having a small equivalent series resistance, is formed by burying a capacitor element inside an epoxy resin outer package. The capacitor element includes an anode, having part of an anode lead buried therein, a dielectric layer formed on the anode and containing a niobium oxide, and a cathode formed on the dielectric layer. The cathode includes a first electrolyte layer containing a conductive polymer and formed on the dielectric layer, an intermediate layer containing an organic silane and formed on the first electrolyte layer, a second electrolyte layer containing a conductive polymer and formed on the intermediate layer, a first conductive layer containing carbon particles and formed on the second electrolyte layer, and a second conductive layer containing silver particles and formed on the first conductive layer.
