PURPOSE:To prevent blurs in printing or coloring on a surface of a bonded magnet formed body by forming thereon a polymer layer having a thickness of a specified value or above. CONSTITUTION:A polymer layer having a thickness of 5mum or above is formed on a surface of a bonded rare earth nitride magnet molded body. The rare earth ferrous nitride is expressed as R-Fe-N-X-Z, where R is one or more selected among rare earth elements and Y (preferably, Sm, Nd, and/or Pr) with its content being 5-20atm% or below of the whole; X is one or more selected among B, Ti, Mo, V, Cr and Co (preferably, B, Cr and/or Co) with the content of (Fe+X) being 40-90atm% (preferably, 70-90atm%) of the whole and X/(Fe+X) being 0-0.49; Z is one or more elements selected among O, H and C with its content being 0-10atm% of the whole.
