Abstract

PURPOSE:To realize high-power and miniature devices, by bringing a permanent magnet into close contact with a ferrite coil with an insulator interposed. CONSTITUTION:Ferrite core 12 and center conductor 13 are arranged on earth table 16 with interposing insulator 15 surrounded by shield plate 11. On the top surface of this ferrite core 12, soft magnetic material 14 is arranged in close contact via shield plate 11 and on its reverse surface, permanent magnet 9 is also arranged in close contact via shield plate 11 and earth plate 16. Since permanent magnet 9 and soft magnetic material 14 are in close contact with ferrite core 12, the effect of radiation is improved and fluctuations of characteristics of the element due to fluctuations of the temperature of the core can be reduced.
