When using the metal housing as a heat dissipation plate or fixing material for electrical components that require heat dissipation, the parts may have to be placed in the housing away from the printed wiring board.In this case, the printed wiring board Wiring is required for connection to and the number of assembling steps increases. Also, when fixing the components on the printed wiring board while mounting them on the printed wiring board, the components on the printed wiring board must be mounted near the housing, that is, at the board edge of the printed wiring board. It had the drawback of being limited. An object of the present invention is to eliminate these drawbacks, to provide a component mounting method which has a small number of components, is inexpensive, and has a large heat radiation effect.
