Abstract
One aspect of the embodiment provides a solid electrolytic capacitor that comprises: an anode; a dielectric layer formed on the surface of this anode; an electrically-conductive polymer layer formed on the dielectric layer; and a cathode layer formed on this electrically-conductive polymer layer. At least manganese is contained in the dielectric layer, and the manganese distributes in a way that the manganese is present more in a part of the dielectric layer that is closer to the cathode (or in the interface between the dielectric layer and the electrically-conductive polymer layer).
