Patent ID: 7663864

Claim:
A rolled electrolytic capacitor, including an electrolyte, comprising: i (i is an integer not smaller than 2) anode members electrically insulated from each other and each having a dielectric coating film on a surface; j (j is an integer satisfying 1≦j<i) cathode members rolled together with said i anode members; k (k is an integer not smaller than 2) separator members arranged at least between said i anode members and said j cathode members, and rolled together with said i anode members and said j cathode members; i anode leads provided corresponding to said i anode members, each connected to an approximately central portion of said corresponding anode member in the lengthwise direction of the corresponding anode member; i cathode leads provided corresponding to said j cathode members, each connected to an approximately central portion of said corresponding cathode member in the lengthwise direction of the corresponding cathode member; an anode terminal connected to said i anode leads; and a cathode terminal connected to said i cathode leads; wherein at least two anode members are initially stacked with respect to one another, said i anode leads have one end connected to said i anode members and the other end opposite to said one end connected to said anode terminal; and said i cathode leads have one end connected to said j cathode members and the other end opposite to said one end connected to said cathode terminal.
