发明名称 RARE-EARTH BONDED MAGNET
摘要 PROBLEM TO BE SOLVED: To provide a new rare-earth bonded magnet where harmful plating liquids and cleaning liquids are prevented from infiltrating the voids portions of the magnet body, and will not deteriorate, such as corrosion resistance to, such as peeling of plating layer corroded from the inside, and whose mechanical strength can be improved. SOLUTION: A mixture, where a rare-earth magnetic powder and a resin binder are mixed in required proportion, is molded to form the magnet body 12, and the parts of voids portion 14 and its surface portion of the magnet body 12 are filled/covered with a carbon powder 16, and the surface portion 12a as a whole of the magnet body 12, including the portions filled/covered with the carbon powder 16, is covered with a metal plated layer 18.
