A sintered rare-earth magnet according to the present invention includes an Nd2Fe14B type crystalline phase as its main phase and Al as an additive. The magnet includes at least one light rare-earth element LR selected from the group consisting of yttrium and the rare-earth elements other than Dy, Ho and Tb, and at least one heavy rare-earth element HR selected from the group consisting of Dy, Ho and Tb. The mole fractions α1, α2 and β of the light and heavy rare-earth elements LR and HR and Al satisfy the inequalities 25≦α1+α2 ≦40 mass%, 00.20 mass%, and 0.04 ≦β/α2≦ 0.12.
