Abstract

In a method for manufacturing a cylindrical bonded magnet, a molding space having a cylindrical shape is filled with a bonded magnet composition containing a magnetic material and a resin. The magnetic material disposed in the molding space is magnetically oriented using an orientation magnet. The orientation magnet includes a first permanent magnet and a second permanent magnet. The first and second permanent magnets are disposed such that same poles are opposite each other in the axial direction.
