Abstract:
1. A solid electrolytic capacitor, comprising: an anode body; a dielectric coating provided on a surface of said anode body; and a first conductive polymer layer provided on said dielectric coating, wherein an anion expressed by a chemical formula (1) below and an organic solvent having a boiling point of 240 Â° C. or higher are included in said first conductive polymer layer: (in the chemical formula (1) above, R1 and R2 are identical with or different from each other, and represent a fluoroalkyl group); a conductive polymer in said first conductive polymer layer is made from polythiophene or derivatives thereof, polypyrrole or derivatives thereof, polyaniline or derivatives thereof, or polyfuran or derivatives thereof, and said anion is present in said first conductive polymer layer in a state where said anion is dissolved in said organic solvent; and a second conductive polymer layer provided on said first conductive polymer layer; wherein said first conductive polymer layer includes more said anion than said second conductive polymer layer.
