Abstract
A first assembly includes a board member for wiring an electric wire thereon, and a first bus bar electrically connected to the electric wire. The first bus bar includes a first tab-shaped terminal having a first dimension in a first direction and a second dimension smaller than the first dimension in a second direction perpendicular to the first direction. A second assembly is joined to the first assembly in the first direction. The second assembly includes a mount section in which an electric component is mounted, and a second bus bar electrically connected to the electric component: The second bus bar includes a second tab-shaped terminal having a third dimension in the first direction and a fourth dimension smaller than the third dimension in the second direction. The first terminal and the second terminal are arranged so as to be overlapped in the second direction to be welded to each other, after the second assembly is joined to the first assembly, and arranged such that a relative position between the first terminal and the second terminal is gradually changed in the first direction during the joining operation of the first assembly and the second assembly.
