Patent ID: 6917514

Claim:
A solid electrolytic capacitor comprising: a valve metal sheet having a porous portion at a first side thereof; a dielectric layer formed on said porous portion; a solid electrolyte layer formed on said dielectric layer; a collector layer formed on said solid electrolyte layer; a through-hole electrode penetrating said valve metal sheet and being exposed to a direction of a second side of said valve metal sheet, said through-hole electrode being connected to said collector layer and being insulated from said valve metal sheet; an electrode terminal exposed to said direction of said second side of said valve metal sheet, said electrode terminal being insulated from said through-hole electrode and connected to said valve metal sheet; an insulating portion penetrating a portion of said valve metal sheet where said dielectric layer, said solid electrolyte layer, and said collector layer are not provided; and a penetration electrode penetrating said insulating portion.
