ABSTRACT:
A battery pack housing a plurality of battery cells in a case and respectively connecting the positive electrodes and the negative electrodes of the plurality of battery cells to conductive terminal boards to be led out to outside terminals is provided. The conductive terminal board has a structure in which a first member is joined with a second member such that the first member having excellent weldability is arrayed in a plurality-of-islands state in the second member having excellent conductivity, and the positive electrodes and the negative electrodes of the battery cell are welded to the first member of the conductive terminal board through resistance-welding, so that the battery pack capable of efficiently supplying a large amount of current is provided.
