<p>A higher harmonic suppressor element 10 includes a higher harmonic coil 12 for suppressing a higher harmonic and a thermal fuse 14 which is connected in series with the higher harmonic coil 12 and also which is melted down by heat generated by the higher harmonic coil 12. The higher harmonic coil 12 and the thermal fuse 14 are both contained in the same envelope body 16. Also, the higher harmonic coil 12 is equipped with a magnetic core 121 and a winding 122 wound around the magnetic core 121. In this configuration, the thermal fuse 14 is in tight contact with the magnetic core by means of an adhesive agent etc. If an over-current flows through the higher harmonic coil 12, it runs hot to thereby melt down the thermal fuse 14. With the melting down of the thermal fuse 14, which is connected in series with the higher harmonic coil 12, the over-current flow to the higher harmonic coil 12 is blocked. <IMAGE></p> |
