PROBLEM TO BE SOLVED : To suppress increase in dimension of a rare-earth bond magnet even when used under a high-temperature environment.SOLUTION : Provided is a rare-earth bond magnet with coating in which coating that contains a second hardened epoxy resin is adhered onto a surface of a rare-earth bond magnet containing rare-earth magnet particles and a first hardened epoxy resin. A glass transition point of the second hardened epoxy resin is higher than that of the first hardened epoxy resin. Preferably, the glass transition point of the first hardened epoxy resin is equal to or more than 130°C.SELECTED DRAWING : NoneCOPYRIGHT : (C)2019, JPO&INPIT
