Abstract: A bus bar is constituted by integrally forming pairs of terminal contact pieces, each pair of which is in contact with an opposed terminal, a pair of connecting base portions, which integrally connect the base-side portions of said terminal contact pieces arranged on the same side thereof, and connecting pieces for connecting the pair of connecting base portions. This bus bar is integrally coupled to a bus bar fixing member constituted by an insulating member. An arbitrary circuit including so-called a skip connection can be constructed by suitably cutting the connecting base portions and the connecting piece. Thus, the entire circuit forming element is constituted as one component.
