    Abstract: R-T-B sintered magnet comprising 12 to 17 atom% rare earth element (R), 5.0 to 8.0 atom% boron (B), 0.1 to 1.0 atom% Al, 0.02 to less than 0.5 atom% Mn and the balance transition metal (T). The rare earth element (R) is at least one member selected from among rare earth elements including Y(yttrium), wherein at least either Nd or Pr is contained. The element of transition metal (T) is composed mainly of Fe.
