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 the 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.

1. A circuit forming element comprising: a bus bar including a plurality of pairs of terminal contact pieces, each pair of which are brought into contact respectively with the terminals opposing with each other provided in the housings adjoining to each other in the stacking direction, a pair of connecting base portions one of which integrally connects proximal ends of said terminal contact pieces disposed at one side while the other connecting base portion integrally connects proximal ends of said terminal contact pieces disposed at the other side, and connecting pieces connecting said pair of connecting base portions; wherein said bus bar is integrally coupled to a bus bar fixing member provided with an insulating member. 2. A circuit forming element according to claim 1, wherein said pair of connecting base portions are offset with respect to each other so that the two connecting base portions do not overlap each other in a plane of projection in a direction of opposing of said connecting base portions to each other. 3. A circuit forming element according to claim 1, wherein proximal ends of said terminal contact pieces are integrally connected to said bus bar fixing member. 4. A circuit forming element according to claim 1, wherein a coupling between said bus bar and said bus bar fixing member is fixed through an opening formed in said bus bar and a protrusion having a flange portion, which is formed on said bus bar fixing member and fitted into the opening by simultaneously forming a partial gap between said protrusion and an inner circumferential portion of said opening. 5. A circuit forming element according to claim 1, wherein cutting portions are selectively formed on said bus bar in the vicinity of portions where said connecting base portion and said connecting piece are connected together. 6. A circuit forming element according to claim 1, wherein a lance for engaging the terminal in a direction to prevent the withdrawal thereof is provided in said terminal accommodating portion for accommodating said terminal, and said bus bar-fixing member has a lance-return regulating portion pressing the lance in a withdrawal prevention direction. 7. A circuit forming element according to claim 1, wherein a chamfered portion is formed at an opposite side edge of said terminal contact piece brought into contact with the terminal. 8. A circuit forming element according to claim 1, wherein a U-shaped bending portion to be folded back on a side edge of said bus bar fixing member is provided in each of said connecting pieces, and wherein said U-shaped bending portions are outwardly exposed.
