A circuit-constituting unit forming a distribution circuit or the like in a vehicle. The circuit-constituting unit includes a plurality of bus bars for constituting a power circuit; a semiconductor switching device provided in the power circuit; and a control circuit board. The bus bars are bonded to a surface of the control circuit board such that the bus bars are arranged to be generally coplanar with each other. The semiconductor switching device is mounted on both of the corresponding bus bars and the control circuit board. An opening may be formed through the control circuit board. In this case, one of terminals of the semiconductor switching device may be connected to a surface of the control circuit board facing away from the surface to which the bus bars are bonded. The other terminals may be connected respectively to the bus bar through the opening.

In the power distributor using a semiconductor switching element, input terminals 10I and 10L, output terminals 12A-12J, connected to the element, and more preferably, the board terminals 30 and 32, are structured by a metallic plate, and arranged on the same plane perpendicular to the plate thickness. The metallic plate can be integrated by the resin mold, thereby the structure can be greatly simplified. The metallic plate can be produced by a greatly simple method by which, after the punching out of the metallic plate and the molding of the resin mold, a predetermined portion of the metallic plate is cut and the semiconductor switching element is mounted, and it can contribute to also the reduction of the cost.

A fuse device is provided with a plurality of separate fuse main bodies in which fuse terminals and fuse terminals are formed at the opposite ends of fusing elements, and a plurality of connection terminals which are members separate from the fuse main bodies. A fuse circuit in which the fusing elements are provided between the connection terminals is formed by directly connecting the fuse terminals of the respective fuse main bodies with the connection terminals. The fusing characteristics of the fusing elements and the strength of the connection terminals can be adjusted without influencing each other.

A distribution unit has a power circuit section including a plurality of bus bars with electronic parts mounted on at least some of the bus bars. Ends of specific bus bars are projected from a main body section of the power circuit section in a adjacent manner to form fuse connection terminals. Each of the fuse connection terminals has a tip placement part to place a fuse terminal. An insulating case made of an insulating material for covering the power circuit section is opened in the projection direction of the fuse connection terminals to enable the fuse terminal to be placed in the tip placement part of the fuse connection terminal from the outside of the insulating case. The insulating case has a short-circuit prevention section intervening between the fuse connection terminals for preventing a short circuit between the fuse connection terminals.
