PROBLEM TO BE SOLVED : To provide an R-T-B-based rare earth sintered magnet having a high coercive force (Hcj). SOLUTION : An R-T-B-based rare earth sintered magnet of the present invention comprises : a rare earth element R; a transition metal T which includes Fe as a main component; a metallic element M which includes one or more metals selected from Al, Ga and Cu; B; and inevitable impurities. The R-T-B-based rare earth sintered magnet contains 13-15.5 atom% of R, 5.0-6.0 atom% of B, 0.1-2.4 atom% of M, and T and the inevitable impurities as a balance, more than 0 atom% and 0.01 atom% or less of Tb being contained as the rare earth element R.
