Abstract

PURPOSE:To enable small size, low cost and the durability against high power, by placing the shield plate enclosing the ground plate and ferrite core and the permanent magnet fixed with the fastening metal fixture projected from the shield plate on the soft magnetic substance closingly. CONSTITUTION:The ground plate 10 is placed on the soft magnetic substance 8 closingly. Further, the shield plate 11 containing one or more ferrite cores 12 and center conductors 13 is placed near the center of the upper part of the ground plate 10. Further, the permanent magnet 9 is fixed with the fastener 21 projected from the shield plate 11 at the upper part of the ferrite core 12. As required, the case 14 is covered.
