Abstract: Disclosed is an aluminum electrolytic capacitor, wherein each of anode and cathode foils is joined to a corresponding portion of a leader line through at least two caulked joint sections formed at each of the opposite ends of the flat portion, and a plurality of pressure-welded joint sections formed between the respective caulked joint sections at the opposite ends. The chaulked joint sections formed at each of the opposite ends of the portion provide a high joint strength. Further, the pressure-welded joint sections formed between the respective caulked-join sections at the opposite ends of the portion allow an electrical connection between the foil and the leader line to be stably obtained at a low resistance. This joint structure can, therefore, be applied to small-size capacitors which have not been able to be obtained by using only caulked joint, to achieve an aluminum electrolytic capacitor having a sufficient joint strength and a highly reliable electrical connection.
