PROBLEM TO BE SOLVED: To provide a method for sealing a cavity on the surface of a bond magnet by which a more excellent sealing effect is obtained than a conventional sealing method. SOLUTION: A bond magnet having a cavity on its surface and a metallic fine powder product substance are housed in a processing container, and kinetic energy is supplied to the housed matter within the processing container. Furthermore, a step (1) where metallic fine powder produced from the metallic fine powder product substance is press-fitted and adhered to the cavity, a step (2) where the bond magnet processed in the step (1) is evacuated and impregnated with processing liquid containing conductive fine powder and an organic dispersion medium, and a step (3) where the bond magnet processed in the step (2) is dried, are conducted successively. |
