The present invention provides a method for producing a rare-earth magnet capable producing a rare-earth magnet exhibiting excellent magnetization and coercive force performance even in the case of a high polar ratio. The method for producing a rare-earth magnet comprises : a step of producing a sintered body which is expressed by the composition formula, (R1_(1-x)R2_x)_aTM_bB_cM_d (R1 is one or more rare earth elements containing Y; R2 is a rare earth element different from R1; TM is a transition metal containing at least one among Fe, Ni, and Co; B is boron; M is one or more among Ti, Ga, Zn, Si, Al, Nb, Zr, Ni, Co, Mn, V, W, Ta, Ge, Cu, Cr, Hf, Mo, P, C, Mg, Hg, Ag, and Au; 0.01 (A1, A2, A3, A4, A5, A6) Pole(BB) Shell(CC) Core(DD) Pole(EE) Grain boundaryCOPYRIGHT KIPO 2015
