Abstract:
Provided is a rare earth magnet that allows suppressing deterioration of magnetic properties and a method for manufacturing the same. The rare earth magnet of the present disclosure includes a magnet body containing a rare earth element R1, a transition metal element T, and boron B and includes a main phase. A region in the vicinity of a corner portion of the magnet body of a constituent surface constituting a surface of the magnet body is a processed surface on which a removal process has been performed, and a region closer to a center than the region in the vicinity of the corner portion of the constituent surface is a non-processed surface on which the removal process is not performed.
