いので、断線が生ずることがない。(Effect of the Invention) As described above, according to the present invention, since the volume of the cutout portion of the magnet for inserting the lead wire is smaller than that of the conventional one, it is possible to increase the bias magnetic field applied to the core. The linearity range of the inductance is widened. Also,
The lead wire spacing is kept constant even by external force.
Since the barbed portion at the end of the winding does not come into contact with the wiring board or the like, disconnection does not occur.
