PROBLEM TO BE SOLVED : To provide a magnetic core having excellent DC superimposing characteristics and corrosion resistance and coil components using this. SOLUTION : This magnetic core is configured by forming a gap in at least one part of a magnetic path, and inserting a bond magnet 10 constituted of rare earth magnetic powder whose unique coercive force is 0.80 kA/m or more, whose curie temperature is 500°C or more, and whose mean particle dimension is 2.5 to 50 μm and resin with resistivity which is 1.0 Ωcm or more into the gap. The particle size distribution of the rare earth magnetic powder is 3 μm or less, and the rate of powder is 10 volume% or less as a whole. COPYRIGHT : (C)2006, JPO&NCIPI
