This invention provides permanent magnets being considerably excellent in not only magnetic properties but also corrosion resistance by using magnetically useful two phases, i.e. RE2TM14B phase having a high residual magnetic flux density and a low melting point RE-TM phase or RE-TM-B phase enhancing the sinterability and possessing a cleaning action against grain boundary of main phase and further forming an electrochemically noble composition as a starting material to prepare a two phase magnet.
