Patent ID: 6882520

Claim:
A solid electrolytic capacitor comprising a capacitor element including an anode body having an anode leading member, and a dielectric coating layer, a solid electrolyte layer and a cathode leading layer which are formed successively over a surface of the anode body, the anode leading member having an anode terminal member connected thereto, the cathode leading layer having a cathode terminal member connected thereto, the capacitor element being covered with a packaging resin portion, the solid electrolytic capacitor being characterized in that the cathode terminal member is connected to the cathode leading layer with current control means provided therebetween, the current control means comprising a current control layer reversibly increasable in electrical resistance with overcurrent or excessive heat, and a pair of electrode members each in the form of a plate or foil and having the current control layer sandwiched therebetween, the electrode members being joined to the cathode leading layer and the cathode terminal member respectively.
