PROBLEM TO BE SOLVED: To disperse thermal stresses for use under a high-temperature environment. SOLUTION: In a magnet body 1, a magnet part 2 and a soft magnetic body part 3 are provided for forming in one piece by a sintering material, and at the same time a composition ratio is changed continuously for the magnet and the soft magnetic body parts 2 and 3. Also, such a magnet body 1 is utilized for a motor. The magnet body 1 is manufactured utilizing centrifugal force.
