Abstract
A solid electrolytic capacitor using a conductive polymer compound as a solid electrolyte includes an anode body, a dielectric oxide coating formed on a surface of the anode body, a first conductive polymer compound layer formed on a portion of the dielectric oxide coating, a silane coupling agent treatment layer formed at least on a portion of the dielectric oxide coating on which the first conductive polymer compound layer is not formed, and a second conductive polymer compound layer formed on the first conductive polymer compound layer and the silane coupling agent treatment layer. With this, a solid electrolytic capacitor having a high capacitance, a low ESR and high reliability and a method of manufacturing the solid electrolytic capacitor can be provided.
