Claims

[Scope of Claim for Utility Model Registration] Two or more layers of a busbar wiring board consisting of an insulating plate provided with a busbar accommodating groove and a plurality of busbars arranged in the busbar accommodating groove, with the busbars standing up from the plate surface. In addition to providing an upright tab and/or a parallel tab extending parallel to the board surface and protruding from the side edge of the insulating board, an interlayer connection portion having a long hole is provided in one layer of the bus bar, and the other layer is connected to the bus bar in one layer. In a laminated busbar wiring board formed by press-fitting interlayer connection tabs provided on busbars of layers, the axial direction of the parallel tabs is located between the parallel tabs and the interlayer connection portion of the busbar having the parallel tabs and the interlayer connection portion. A laminated busbar wiring board characterized by having a crank part that absorbs external force applied to the busbar.
