Method for producing solid electrolytic capacitor

A method for manufacturing a solid electrolytic capacitor comprising:

• providing an aluminum foil having first and second surfaces,
• forming a porous portion on the first surface of said aluminum foil,
• forming a dielectric layer on said porous portion,
• forming a through hole having an inner wall surface at first location in said aluminum foil,
• forming a resist portion at a second location on said aluminum foil,
• forming an insulation layer on said aluminum foil to cover both the second surface that is opposite the first surface and the inner wall surface of said through hole,
• forming a solid electrolytic layer on said dielectric layer,
• forming a through hole electrode having an exposed surface in said through hole,
• forming a collector layer on said solid electrolytic layer,
• forming an opening in said insulation layer at said second location in said aluminum foil by peeling said resist portion, and
• locating a connection terminal at said opening in said insulation layer and on the exposed surface of said through hole electrode.
