Abstract: A rare earth bonded magnet obtained by mixing two types of magnetic powders (A) and (B) in the present invention has a high residual magnetic flux density (Br), a large intrinsic coercive force (iHc) and a large maximum energy product ((BH)max) in spite of a low rare earth element content, and shows an excellent rust preventability. A rare earth-iron-boron type magnet alloy of the present invention has a residual magnetic flux density (Br) as high as not less than 10 kG, an intrinsic coercive force (iHc) as large as not less than 3.5 kOe and a large maximum energy product ((BH)max) and which has an excellent rust preventability.
