US Patent 7573699 Solid state electrolyte capacitor and manufacturing method thereof

A solid electrolytic capacitor, including a stack of solid electrolytic capacitor elements each having an anode part and a cathode part. The stacked structure is such that cathode parts of solid electrolytic capacitor elements are stacked one on another to have some misalignment between the stacked elements. The capacitor preferably has a structure in which one end part of the cathode part of at least one of the solid electrolytic capacitor elements stacked on another element is more prominent or retracted than that of the element below.
