A cylindrical bonded magnet is provided which is multipolar-magnetized in the axial direction and can be produced with high productivity. The cylindrical bonded magnet includes magnetic powder and resin. The cylindrical bond magnet is an integrally formed member. The cylindrical bond magnet is magnetized so that a plurality of N and S poles are alternately provided in the axial direction. In the cylindrical bonded magnet, a totally even number of at least four N and S poles are alternately provided. The surface magnetic flux density distribution has a substantially sinusoidal wave with the both ends of the sinusoidal wave corresponding to nodes when the surface magnetic flux of the cylindrical bonded magnet is measured as viewed from the side surface of the cylindrical bond magnet along the axial direction.
