摘要： A coil component (100) comprises a coil-containing insulator enclosure and a magnetic core (80). The coil-containing insulator enclosure can be obtained by enclosing a coil (30), except for end portions (12, 22) of the coil (30), with an insulator (50), wherein the insulator (50) comprises at least first resin. The magnetic core (80) is made of a mixture of a second resin (82) and powder, which comprises at least magnetic powder (84). The coil-containing insulator enclosure is embedded in the magnetic core (80).

摘要： A magnetic core is obtained by hardening or curing a mixture of magnetic powder and resin. The magnetic core shows a superior DC bias characteristic which does not become drastically saturated but is gently saturated even beyond 1000 * 10 3 /4π [A/m]. Therefore, the magnetic core has sufficient relative permeability more than ten.

摘要： Disposed in a magnetic gap of a magnetic core, a magnetically biasing permanent magnet is a bond magnet comprising rare-earth magnetic powder and a binder resin. The rare-earth magnetic powder has an intrinsic coercive force of 5kOe or more, a Curie temperature of 300°C or more, and an average particle size of 2.0-50µm. The rare-earth magnetic power has a surface coated with a metallic layer containing an oxidation-resistant metal. In order to enable a surface-mount to reflow, the rare-earth magnetic powder may have the intrinsic coercive force of 10kOe or more, the Curie temperature of 500°C and the average particle size of 2.5-50µm. In addition, to prevent specific resistance from degrading, the metallic layer desirably may be coated with a glass layer consisting of low-melting glass having a softening point less than a melting point of the oxidation-resistant metal.
