Abstract
A conductive polymer composition with excellent water resistance and conductivity, and a solid electrolytic capacitor with low ESR, excellent reliability, and especially moisture resistance. The conductive polymer composition includes a conductive polymer, a polyanion that includes a hydrophilic group, where the polyanion functioning as a dopant of the conductive polymer. At least a part of the hydrophilic group of the polyanion is condensed with an epoxy group in a compound with one epoxy group. A solid electrolytic capacitor of the present invention includes the conductive polymer composition.
