<P>PROBLEM TO BE SOLVED: To provide a magnetic core, an inductance component using it, and its manufacturing method wherein, even if they are used in a region exceeding 110 kA/m, an excellent DC current superposition characteristic is exhibited without causing magnetic saturation with by achieving low noise. <P>SOLUTION: The inductance component comprises magnetic cores 3a, 3b made by blending magnetic powder and resin, a winding 4 obtained by winding a conducting wire, an insulating layer 2a for covering the surface of the winding 4, and an accommodation case 5 for accommodating these members. In the inductance component, magnetic powder constituting the magnetic cores 3a, 3b is composed of at least two kinds or more of magnetic powder of magnetic powder of which the magnetic distortion characteristic is positive and magnetic powder of which the magnetic distortion characteristic is negative. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
