A rare earth magnet having a main phase and a sub-phase, wherein the main phase has a ThMn12-type crystal structure; the sub-phase contains at least any one of an Sm5Fe17-based phase, an SmCo5-based phase, an Sm2O3-based phase, and an Sm7Cu3-based phase; assuming that the volume of the rare earth magnet is 100%, the volume fraction of the sub-phase is from 2.3 to 9.5% and the volume fraction of an α-Fe phase is 9.0% or less; and the density of the rare earth magnet is 7.0 g/cm3 or more.
