PURPOSE:To improve the oxidation resistance of an R (rare-earth elements)-Fe- Co-B magnet. CONSTITUTION:This R-Fe-Co-B-C bond magnet is constituted of the powder of an R-FE-Co-B-C magnetic alloy (R: at least one of rare earth elements including Y) containing magnetic crystal grains, each of which contains <=16wt.% (excluding 0wt.%) of C and <=30wt.% (excluding 0wt.%) of Co and is coated with an oxidation-resistance protective film, and a resin component, with the volume percentage of the resin component being adjusted to <=50%. |
