PROBLEM TO BE SOLVED : To provide an inexpensive magnetic core having superior coreloss characteristics and DC superimposing characteristics, and to provide an inductance component using the magnetic core.
SOLUTION : The inductance component is constituted of the magnetic core 11 having gaps into which bonded magnets are inserted at least one or more places of its magnetic path and a winding 4 wound around the magnetic core 11 by at least one turn or more. Each bonded magnet has an intrinsic coercive force of ≥10 kOe, a Tc of ≥500°C, and a specific resistance of ≥1.0 Ωcm, is composed of rare-earth magnet powder having a mean particle diameter of 2.5-50 μm and a resin, and is suppressed in the increase of the hysteresis loss of its core to ≤20% as compared with that before insertion. |
