A method for manufacturing a magnetized bonded magnet, including the steps of : arranging a magnetization permanent magnet for magnetizing a magnetic field near a non-magnetized bonded magnet; heating the non-magnetized bonded magnet to a temperature of a Curie point thereof or higher; and continuously magnetizing the magnetic field to the non-magnetized bonded magnet by the magnetization permanent magnet for magnetizing the magnetic field while cooling the non-magnetized bonded magnet reached at the temperature of the Curie point thereof or higher to a temperature of less than the Curie point, wherein the non-magnetized bonded magnet is a rare-earth iron bonded magnet including two or more different rare-earth elements in magnet powder thereof.
