PROBLEM TO BE SOLVED: To provide a magnetic core capable of being manufactured even by a simple method and also having high strength, high specific resistance and high corrosion resistance, and a coil component using the magnetic core.SOLUTION: A magnetic core has a structure in which Fe-based soft magnetic alloy particles are dispersed. The Fe-based soft magnetic alloy particles include Al and Cr, and are bound to each other via an oxide layer formed on the surface of the particles. In measuring the color and color difference on a surface of the magnetic core, a(D65) is from -3.0 to 1.0 in a Labcolor system and/or b(D65) is from -7.0 to 1.0 in the color system.SELECTED DRAWING: Figure 2 |
