PROBLEM TO BE SOLVED: To provide a method of manufacturing an anisotropic resin permanent magnet which makes it possible to form an anisotropic permanent magnet of an inexpensive metallic hollow tube without using an expensive molding die and ground into power, and the powder and resin are mixed together and formed into an anisotropic resin permanent magnet. SOLUTION: An anisotropic permanent magnet is manufactured through following three processes, a first process where magnetic powder 50 is filled up into a hollow tube 52 to the brim, a second process where the magnetic powder 50 and the hollow tube 52 are hot-compressed together at temperatures of 400 to 1000 deg.C to turn the magnetic powder 50 into a permanent magnet of high density, and a third process where the permanent magnet is hot- processed to turn magnetically anisotropic for the formation of an anisotropic permanent magnet 56. |
