Abstract
A solid electrolytic capacitor formed with a dielectric coating and a solid electrolyte layer successively formed on a surface of an anode body, wherein the solid electrolyte layer includes a conductive polymer containing at least a fluoroalkylnaphthalenesulfonate ion as a dopant. The conductive polymer can further contain a tetrahydronaphthalenesulfonate ion, a naphthalenesulfonate ion or a benzenesulfonate ion as the dopant. As a result, a solid electrolytic capacitor having a low ESR and a good heat resistance is provided.
