Abstract

PURPOSE:To elevate the electric power resisting characteristic and make the apparatus small-sized, by making a permanent magnet provided so as to be opposed to a ferrite core adhere closely to the ferrite core. CONSTITUTION:In the inside of the case 1, a ferrite core 6 and a center conductor 7 are surrounded by the shield plate 5, and are installed onto the earth base 4. On the upper surface of this ferrite core 6, a permanent magnet 3b is installed and is made to adhere closely through the shield plate 5, and on the lower surface of the ferrite core 6, a permanent magnet 3a is installed and is made to adhere closely through the shield plate 5 and the earth plate 4. In this way, since the permanent magnets 3a, 3b are made to adhere closely to the ferrite core 6, the heat radiation becomes satisfactory, and the electric power resisting characteristic is elevated. In addition, since there is no space between the ferrite core 6 and the permanent magnets 3a, 3b, the apparatus is made small-sized.
