PROBLEM TO BE SOLVED: To simplify the structure of a periphery of a sealing port, and to improve reliability and productivity of battery by using a metal round bar, of which one part is worked flat so as to form a flat part, and a tab terminal, which is welded to an end surface of the round bar so as to form a lead wire, as a lead member. SOLUTION: As a lead member of a positive electrode and a negative electrode, tab terminals 6, 7 having the nearly same shape with a tab terminal for aluminum electrolyte capacitor are used. One end of each tab terminal 6, 7 is formed with a metal round bar, which has a flat part formed into flat, at one end thereof, and a lead wire 2 is welded to an end surface of this round bar. The round bar of the tab terminal 6 of the positive electrode is made of aluminum as same as the material of a collector 1, and the round bar of the tab terminal 7 of the negative electrode is made of copper as same as the material of a collector 3. A sealing body 8 is formed with insertion holes for the tab terminals 6, 7, and the sealing body 8 is housed in a metal case 9 with a power generating element in the condition that the tab terminals 6, 7 are inserted therein. |
