<P>PROBLEM TO BE SOLVED: To provide a composite magnetic material excellent in suppression of iron loss in a high-frequency band and having a required effective magnetic permeability, and a dust core using the same and a magnetic element. <P>SOLUTION: The composite magnetic material is formed by mixing a soft magnetic alloy material and a binding resin of 1-10 wt.% to the soft magnetic alloy material. The soft magnetic alloy material is prepared by mixing 0-90 wt.% (including 0 wt.%) a material having an amorphous structure in addition to a material having a nano-sized crystalline structure into the entire soft magnetic alloy material, and the average grain size of the powder is not more than 50 μm. The composite magnetic material is used to manufacture the dust core and the magnetic element. <P>COPYRIGHT: (C)2007,JPO&INPIT |
