PROBLEM TO BE SOLVED: To provide a compact and lightweight busbar.SOLUTION: A busbar 10 is stamped from a single metal plate 10' and then folded along alternate long and two short dashes lines. The busbar 10 has: a power input part 1 for power input; a tuning fork terminal part 2 for insertion of a relay terminal; a plurality of board connection parts 3, 4, 5 for soldering to a printed board 6; and a routing part 16. The routing part 16 has: a trunk portion 11 extending in a band from the power input part 1, and a plurality of branch portions 12, 13, 14, 15 branching off from the trunk portion 11 toward the tuning fork terminal part 2 and the board connection parts 3, 4, 5. The trunk portion 11 has a width narrowing down stepwise with distance from the power input part 1. Specifically, the trunk portion 11 has widths W3, W4 of portions more distant from the power input part 1 than the branch portion 12 made narrower than a width W1 of a portion from the power input part 1 to the branch portion 12. |
