<P>PROBLEM TO BE SOLVED: To provide an anisotropic sintered permanent magnet for improving skew in a magnetization easy axis direction by contriving a press forming condition at press forming in a magnetic field in a manufacturing process of the anisotropic sintered permanent magnet, and to provide a manufacturing method thereof. <P>SOLUTION: The skew in the magnetization easy axis direction is improved by adjusting a moving distance of upper and lower punches with respect to dies to (A-B)/2 mm±0.2×(A-B)/2 mm in the press forming process under the magnetic field, wherein A is a height of raw material powder in a cavity at filling the raw material powder, and B is a height of a press body after the powder is compressed and formed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
