摘要：A permanent magnet which is a bonded magnet comprising a magnet powder and a resin in a resin content of 20 vol % or higher and has a resistivity of 0.1 Φ cm or more, wherein the magnet powder is a rare earth magnet powder having an intrinsic coercive force of 5 kOe or more, a Curie point Tc of 300 ° or higher and an average particle diameter of 2.0 νm to 50 νm. The permanent magnet can be suitably ud as a bias magnet which is arranged at a gap of a magnetic core in order to impart excellent direct current superimposing characteristics and also excellent core loss characteristics to the magnetic core. For u in a magnetic core of inductance parts which are subjected to soldering reflow treatment, a bonded magnet having a resin content of 30 % or more is ud, wherein u is made of a Sm-Co magnet powder having an intrinsic coercive force of 10 kOe or more, a Curie point Tc of 500 ° or higher and an average particle diameter of 2.5 νm or more. This bonded magnet permits the preparation of a thin plate magnet
having a thickness of 500 νm or less for u in inductance parts of the miniature size.
