| 简介 |
Provided is a rare earth-based bonded magnet which exhibits excellent magnetic characteristics due to improved oxidation resistance under high temperatures. The magnet has a magnet body (10) that comprises a magnet powder (11) containing a rare-earth element and a resin part (12) for holding the magnet powder (11) and wherein the magnet powder (11) is embedded in the resin part (12), and an amorphous carbon film (91) which is formed directly on the surface of the magnet body (10). The resin part (12) comprises a binder resin part (14) that holds the magnet powder (11) and a resin layer (13) which is positioned on the surface layer of the magnet body (10) to cover the magnet powder (11). The binder resin part (14) and the resin layer (13) may be made of the same resin material, and may also be integrally continuous with each other. |
