PROBLEM TO BE SOLVED : To provide a rare earth bond magnet, excellent in magnetic flux density, having density higher than density of a compact before heat hardening.
SOLUTION : The rare-earth-ferrous bond magnet formed by making a rare-earth-ferrous magnet compound containing rare-earth-ferrous magnet flakes and a thermosetting resin composition, press-molding the compound to make a compressed compact, and heat hardening the compressed compact has density higher than density of the compressed compact before heat hardening, with heating hardening of the compressed compact.
