PROBLEM TO BE SOLVED: To provide a capacitor which is equipped with a stable junction part between an electrode plate and a collector plate, and has a collecting structure suitable for large current discharge. SOLUTION: There are provided a capacitor element 4 in which an anode plate 1 and a cathode plate 2 are arranged through a porous insulating layer 3 while end parts 1a and 2a of the anode plate 1 and the cathode plate 2 are protruded from the porous insulating layer 3, and collector plates 10 and 11, with a protruding part 12 comprising a gap part 12a formed inside. While electrode plate end parts 1a and 2a protruding from the porous insulating layer 3 are made to abut with the main surface of the collector plates 10 and 11, the protruding part 12 is locally heated so that the electrode plate end parts 1a and 2a are jointed to the collector plates 10 and 11. The electrode plate end parts 1a and 2a are welded to the collector plates 10 and 11 by a molten member generated as the protruding part 12 is melted. COPYRIGHT: (C)2008,JPO&INPIT
