<p><P>PROBLEM TO BE SOLVED: To provide a high-performance molding material of high permeability, high insulation and a high withstand voltage. <P>SOLUTION: The magnetic body molding material comprises composite magnetic body powder and a resin, and filling is performed so that the volume filling rate of the composite magnetic body powder becomes≥60 Vol%. The composite magnetic body powder consists of magnetic body powder and low-melting glass which covers the surface, and the low-melting glass is turned to such a covering state that remarkable oxidization is not visually confirmed on the surface of the magnetic body powder even when the composite magnetic powder is immersed in salt water for one day or longer. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
