<p>PROBLEM TO BE SOLVED: To increase heat radiation and current carrying by welding, at a specified place of a pattern section of a bus bar, a welding member which has at least a first section crossing at right angles with the pattern section and a second section parallel with the pattern section. SOLUTION: On a pattern section 200 of one bus bar, for example, the one in the most outer layer out of a plurality of stacked bus bars, a welding member 100 is fixed by welding. The welding member 100 has a second section 110, a welded part, parallel with the pattern section 200 of the bus bar and a first section 120, a heat radiation part, nearly at right angles with the pattern section 200. Generally, the larger surface area the welding member 100, especially the radiation part 120, has, larger heat radiation can be obtained. In this case, the welding member 100 having the heat radiation part 120 of a large surface area is welded to the pattern section 200 of the bus bar, the increase in temperature of the bus bar can be suppressed.</p> |
