The problem with the above arrangement is that the opposite side opposing the one side rotates around the outer periphery of the bobbin about one side through which the core penetrates the center axis portion of the bobbin. That is, the magnetic flux is easily affected by the leakage magnetic flux to other portions, or noise is likely to enter the core. Therefore, an object of the present invention is to suppress the magnetic influence on other components due to the leakage magnetic flux from the core and to eliminate the intrusion of noise into the core.
