Thus, heating and cooling of a sheet metal which are necessary when soldering a sheet metal having large heat capacity in the past is not required, so that the productivity can be improved and the cost can be reduced. Besides, the sheet metal part 63 and an L-shaped bent part 64 of the connecting pin 6 make contact with the sheet metal 1 and the printed circuit board 3; therefore, the connection is stable. Furthermore, the surface area of the connecting pin 6 is enlarged by the L-shaped bent part 64 and consequently a contact area with the sheet metal 1 and the printed circuit board 3 is increased; therefore, the vibration resistance and the heat dissipation are improved.
