Abstract
A method of fabricating a solid electrolytic capacitor of an aspect includes the steps of preparing an anode element with a dielectric layer formed on a surface thereof, forming a solid electrolytic layer on the dielectric layer, forming a carbon layer on the solid electrolytic layer, bringing an aqueous polymer into contact with the carbon layer, and forming a silver paste layer on the aqueous polymer. A method of fabricating a solid electrolytic capacitor and a solid electrolytic capacitor that can be improved in characteristics can thus be obtained.
