PURPOSE:To obtain a high orientation bond magnet wherein the magnetic characteristics are improved by forming rare earth magnet powder in a radial orientation magnetic field when the powder has coercive force of, 6 kOe or less before aging treatment and then by aging it. CONSTITUTION:2-17: system rare earth magnet power is formed in a radial orientation magnetic field when the powder has 6 kOe or less low coercive force before age treatment. Then, the formed powder is aged. The 2-17 system rare earth magnet powder has a main component of a composition shown by R2TM17 (where, R is one or two or more of rare earth elements such as Sn, Ce, Pr and Nd, including Y and TM is one or two or more of transition metal elements such as Fe, Co, and Ni). This enables obtaining a high orientation bond magnet wherein the magnetic characteristics are improved.
