As shown in FIG. 5, a U-shaped conductor 4 is arranged around a central through-hole 7 on a bobbin with a terminal for a coil 1 in which a plurality of terminals 2 are processed on left and right ends. Then, the end is electrically connected and fixed to the terminal 2, and if necessary, an insulating sheet or the like is disposed therebetween, and the next U-shaped conductor 4 is connected to the terminal 2 shifted by one, and a through hole is formed. A coil having one less number of turns than the number of terminals N is formed around the coil 7, and then the center magnetic leg of the magnetic core 5 is made to pass through the through hole 7 of the bobbin with a coil terminal, thereby producing a coil. Also, as shown in FIG. 6, coils are formed on the left and right sides of the magnetic core 5 one by one as in FIG. Conventionally, two coils on both sides having one less number of turns than the number N of terminals on one side are externally connected and used as 2N-2 turns. Therefore, the number of turns of the coil is determined by the number of terminals on one side of the bobbin, and there is a problem that the number of turns of the coil cannot be sufficiently obtained, or that there is a problem that a new external connection is required.
