PROBLEM TO BE SOLVED: To provide a rare-earth magnet that improves the electrical resistance as a whole, significantly improves texture nonuniformity, and is superior in quality and reliability, and to provide a method of manufacturing the magnet. SOLUTION: In this rare-earth magnet, the volume of an Nd2 Fe14 B crystalline phase 1 occupies >=90% of the whole volume of the magnet. The crystalline phase 1 has a mean crystal grain diameter of 1-10 μm and >=80% of its grain boundary phase is an amorphous phase 2. |
