<P>PROBLEM TO BE SOLVED: To obtain high insulation and voltage resistance property along with high effective magnetic permeability property in an inductor. <P>SOLUTION: A magnetic material covers such a surface of magnetic metallic powder, hard Fe-Si system alloy magnetic powder, or ductile Fe-Ni system alloy magnetic powder with glass membrane, and covers the outside with thermosetting resin which serves both as an insulating material and a binding material. Further, an air core coil 1 is embedded into the powder consisting of the magnetic material, so that an inductor may be constituted by carrying out pressure molding. <P>COPYRIGHT: (C)2007,JPO&INPIT |
