Patent ID: 8419809

Claim:
A method of manufacturing a solid electrolytic capacitor including an anode element having a dielectric film formed on its surface and a conductive polymer layer formed on said dielectric film, comprising the steps of: adhering particles made of conductive polymer or aggregates made of conductive polymer onto said anode element by bringing a dispersion in which said particles made of conductive polymer or aggregates made of conductive polymer are dispersed in the first solvent into contact with said anode element having said dielectric film formed thereon; washing said anode element onto which said particles made of conductive polymer or said aggregates made of conductive polymer are adhered with a second solvent higher in boiling point than said first solvent, in which said particles made of conductive polymer or said aggregates made of said conductive polymer can be dispersed; and drying said anode element washed with said second solvent at a temperature not lower than the boiling point of said first solvent and lower than the boiling point of said second solvent.
