BUS BAR, AND METHOD FOR PRODUCING BUS BAR

摘要

PROBLEM TO BE SOLVED: To provide a bus bar capable of restraining electric resistance while preventing electric corrosion and excellent in mechanical strength, as one used for a battery with a positive terminal and a negative terminal formed of mutually different kinds of metal.SOLUTION: The bus bar 1 has a positive electrode connecting part 10 formed of the same metal as that for the positive terminal 5 of a battery cell 2 and enabled to be connected to the positive terminal 5 and a negative electrode connecting part 11 formed of the same metal as that for the negative terminal 6 of the battery cell 2 and enabled to be connected to the negative terminal 6, wherein the positive electrode connecting part 10 and the negative electrode connecting part 11 are bonded in one piece by means of metallic bonding.
