Abstract
A method for manufacturing a solid electrolytic capacitor is described. The method comprises providing a valve metal member which has a dielectric film and an inorganic conductive layer formed on opposite sides of the valve metal member in this order, immersing the valve metal member in an electrolytic polymerization solution, and applying an electric potential sufficient to cause electrolytic polymerization between a first polymerization electrode which is provided on said at least one side of said valve metal member through an electric insulating member and a second polymerization electrode kept away from said first polymerization electrode. Further, the valve metal member may be separated into two regions with an insulating separation layer. One region is a capacitor region and the other is an anode terminal region. The anode terminal region is enfolded or convolutely wound to improve the volumetric efficiency. Solid electrolytic capacitors manufactured by the methods are also described.
