PURPOSE:To save the components and reduce the cost by a method wherein metal fittings which fix a core on a printed circuit board are connected so as to form a coil. CONSTITUTION:A core 1 is fixed on one side of a printed circuit board 6 by a plurality of metal fittings 7. On another side of the board 6, the both ends of the fittings 7 come out through holes 9 provided to a pattern 8 and are connected in such a manner that the fittings 7-1-7-5 and 7-6-7-10 form one continuous coil. With this constitution, the metal fittings are utilized as a part of the coil so that the number of components is reduced and the cost can be saved. |
