Patent ID: 6852137

Claim:
A method for manufacturing solid electrolytic capacitor comprising the steps of; forming a resist film on one of the surfaces of an aluminum foil, forming a first through hole at a certain specific location of said aluminum foil, forming an insulation film covering the other surface which is opposite to the one having said resist film and filling said first through hole of said aluminum foil, roughening the surface of said aluminum foil in the region where said resist film used to be and removed, forming a dielectric layer on the roughened surface of said aluminum foil, forming a second through hole in said insulation film filling said first through hole, forming a through hole electrode in said second through hole and then forming a solid electrolytic layer on the surface of said dielectric layer, forming a collector layer on the surface of said solid electrolytic layer, forming an opening in said insulation film, forming a first connection terminal at said opening, and forming a second connection terminal on exposed surface of said through hole electrode.
