Method of manufacturing solid electrolytic capacitor.

摘要

The invention provides a method for manufacturing a solid electrolytic capacitor having oxide film (4) of valve action metal (1) as a dielectric substance and conducting polymer as solid electrolyte. The method includes the steps of forming solid monomer compound on a surface of the oxide film (4) by applying monomer compound solution to the surface and then drying the monomer compound solution, and forming a conducting polymer layer (5) by polymerizing the solid monomer compound with an oxidizer. The method provides a capacitor having a quite small impedance in a resonant frequency and also having a superior high frequency characteristic.
