PROBLEM TO BE SOLVED : To achieve easier suppression of an overcurrent by increasing an electrical resistance than a conventional rare-earth sintered magnet. SOLUTION : The rare-earth sintered magnet is a rare-earth sinter magnet containing a main phase and a grain boundary. The grain boundary includes a region with higher electrical resistance than the main phase. SELECTED DRAWING : None COPYRIGHT : (C)2017, JPO&INPIT
