Abstract
A solid electrolytic capacitor of the present invention includes a sheet of valve metal, of which a part constitutes an positive electrode, a dielectric layer formed on a surface of the valve metal, a solid electrolyte layer formed on the dielectric layer, a negative electrode formed on the solid electrolyte layer, and an insulating protective layer for protecting the positive electrode, the dielectric layer, the solid electrolyte layer and the negative electrode. It is further provided with a bump formed on the insulating protective layer and connected to at least one of the positive electrode and the negative electrode. The solid electrolytic capacitor of the present invention is useful to constitute a semiconductor device or a circuit having outstanding high frequency response.
