<p>PROBLEM TO BE SOLVED: To greatly weld a tab terminal to a busbar with less amount of energy by laser. SOLUTION: In busbar structure that is accommodated in an electrical connection box and where tab terminals in upper and lower directions are formed on a pattern part, bending margin parts 7d' and 7e' of a pair of separate tap terminals 7d and 7e are applied to the upper and lower surfaces of the pattern part of a busbar 7, respectively, so that they are symmetrical in upper and lower directions, and the welding position between the bending margin part 7e' of the upper tap terminal 7e and the bending margin part 7d' of the lower tap terminal 7d is shifted, thus performing laser welding a and a'.</p> |
