Patent ID: 7099145

Claim:
A solid electrolytic capacitor comprising: at least one solid electrolytic capacitor component comprising a foil-like valve metal substrate formed with an insulating oxide film on the surface thereof; at least one lead electrode pair including an anode lead electrode and a cathode lead electrode which are provided on at least one end portion region of the foil-like valve metal substrate; and a cathode electrode formed by sequentially forming at least a solid high molecular polymer electrolyte layer and a conductive layer on the foil-like valve metal substrate; the anode lead electrode comprising a valve metal body whose one end portion region is bonded to the at least one end portion region of the foil-like valve metal substrate so that electrical connection can be established between the valve metals and a first conductive metal substrate whose one end portion region is bonded to the other end portion region of the foil-like valve metal substrate so that electrical connection can be established between the metals; the cathode lead electrode being formed by drawing out a part of a second conductive metal substrate connected to one surface of the conductive layer formed on the foil-like valve metal substrate in a direction parallel to the anode lead electrode.
