SHIELDING DEVICE

摘要

PURPOSE:To realize the rationalization of production process and the cost down as well as the ultraminiaturization of shielding device by a method wherein a space around winding coils is filled with insulator while a shielding metal is formed into one body on the surface of insulator. CONSTITUTION:A space around winding coils 3 is filled with an insulator 2 while a shielding metal 1 is formed into one body on the surface of the insulator 2. In such a constitution, the title shielding device can be formed into one body with a winding coils to realize the rationalization of production process as well as an ultraminiaturization of the device.
