PURPOSE:To obtain a main lead body which causes no such harm as an internal short circuit by fixing a part of an auxiliary lead body to the outer surface of a negative can by a spot welding or something similar before the negative can is used for the assembly of a battery, and extending the free end side of the auxiliary lead body before the free end is connected to a main lead body. CONSTITUTION:A metallic net 7 is fixed on the inner wall of a negative can 2 by a spot welding, and a negative electrode 5 made of lithium metal is pressed and fixed upon the net 7 so as to hold the negative electrode 5 and to make the negative can 2 and the electrode 5 to be electrically connected. A gasket 6 consisting of a formed synthetic-resin member is closely attached around the outer circumference of the can 2. After a positive electrode 3 made of mixture consisting of manganese dioxide and a conductive auxiliary agent is inserted onto the bottom of a positive can 1, a separator 4 made of a non-woven fabric consisting of polypropylene fiber is placed on the electrode 3. After that, the negative can 2 is attached to the opening of the positive can 1, and the opening of the can 1 is inwardly curled so as to caulk the battery, thereby constituting a battery. An auxiliary lead body 11 is extended along a cut 13, and a main lead body 14 on the negative electrode side is connected to the free end of the lead body 11 by a spot welding 15. A main lead body 16 on the positive electrode side is directly connected to the lower surface of the positive can 1 by a spot welding 17. |
