PROBLEM TO BE SOLVED: To provide a resin magnet composition which can be formed into a rare earth bonded magnet that will not deteriorate in magnetic characteristics, even in an environment of high-temperature and high-humidity. SOLUTION: Magnetic powder is mixed and dispersed into a resin binder for the formation of a resin magnet composition, where the surface of the magnetic powder is subjected to hydrophobic treatment, and 2 to 40 wt.% resin binder and 98 to 60 wt.% magnetic powder are mixed together. |
