1. A rare earth magnet comprising:a main phase;
a grain boundary phase present around the main phase; and
an intermediate phase interposed between the main phase and the grain boundary phase,
wherein the rare earth magnet has an overall composition represented by ((Ce(1-x)Lax)(1-y)R1y)pT(100-p-q-r)BqM1r?(R21-zM2z)s, where R1 and R2 are rare earth elements other than Ce and La, T is at least one selected from among Fe, Ni, and Co, M1 is at least one selected from among Ti, Ga, Zn, Si, Al, Nb, Zr, Mn, V, W, Ta, Ge, Cu, Cr, Hf, Mo, P, C, Mg, Hg, Ag, and Au, and first inevitable impurities, M2 is (i) an alloy element for which a melting point of R21-zM2z is lower than a melting point of R2 when M2 is alloyed with R2 and (ii) second inevitable impurities, and p, q, r, s, x, y, and z satisfy
wherein a total concentration of Ce and La is higher in the main phase than in the intermediate phase,
wherein a concentration of R2 is higher in the intermediate phase than in the main phase, and
wherein a concentration of La is higher in the grain boundary phase than in the intermediate phase.
