The magnet material comprises 10-40 atom % of at least one rare earth elements selected from La, Ce, Pr, Nd, Sm and Dy, 2-10 atom % boron and balance of at least one metals selected from Fe, Al, Co, Nb, Ti, Cr, Zr, Hf and V, the metals containing 0.1-5.0 atom % of at least one elements selected from S, P and C. The method for manufacturing a permanent magnet is characterized by sintering the composed powder at 1,000-1,200 deg.C for 0.5-2.0 hours and heating at 500-750 deg.C for 0.5-2.0 hours under the vacuum.
