ABSTRACT:
A method for fabricating solid electrolytic capacitors which comprises providing a valve metal foil having a dielectric film and a conductive inorganic film formed on the valve metal foil in this order, contacting an electrode for electrolytic polymerization with part of the valve metal foil wherein the electrode is made of a material incapable of undergoing anodization in an electrolytic polymerization solution, subjecting the valve metal foil to electrolytic polymerization by application of a potential between the electrode and a counter electrode to form a conductive polymer film on the conductive inorganic film, and removing the electrode along with the contacted portion of the valve metal foil. At least one conductive paste film may be formed on the conductive polymer film prior to the removal of the electrode. In addition, an insulating film may be formed on an exposed portion of the valve metal foil after the removal of the electrode. A fabrication method of a capacitor unit having at least two capacitor elements is also described.
