Dy, not including the rare earth metals such as Tb in the grain boundary phase, it is at a low temperature reforming alloy to increase the coercive force (coercivity under especially high temperature) is penetrated as compared to the conventional rare-earth magnet, therefore, a high coercive force, the magnetization is relatively It provides a high rare-earth magnet and method of manufacturing the same. RE-Fe-B of the nano-crystal structure type (RE: Nd, at least a kind of Pr) of the main phase (MP) and the main phase (MP) RE-X alloy (X being around of: a metal element and of containing a rare earth element made of a grain boundary phase (BP) of no), respectively, of the main phase (MP) is and is oriented in the anisotropic axis, also, it is in the direction perpendicular to an anisotropic axis in a square or this plan-view shape of the pillar-shaped stunning shape which it is a rare earth magnet (RM).
