Abstract

PURPOSE:To enable the magnetic force of a permanent magnet to be effectively utilized while preventing magnet dust from falling off by coating a surface of the permanent magnet, formed by a sintered body of powdery magnetic material, with an evaporation film. CONSTITUTION:A permanent magnet, for instance, sintered alnico ferrite magnet and a rare earth magnet or the like are formed by a sintered body of powdery magnetic material, coating their surface with an evaporation film. It is preferable for the coating material to use, for instance, xylene resin and polyimide resin or the like. It is preferable for the xylene resin to use poly-p-xyline, polymonochloro-p-xylene, polydichloro-p-xylene, etc. In the evaporation method of the coating material, the method is cited such as, for instance, PVD of vacuum evaporation, ion plating, sputtering evaporation, etc., or plasma CVD, pressure reducing CVD, normal pressure CVD, etc.
