SOLUTION: A magnet rotor 100 is an inner rotor, having a motor shaft hole 110 and is a magnet corresponding to 5 to 10 poles. In the magnet, a first and a second gear-shaped rotor parts 120A, 120B, where magnetic pole protruding parts 121 and trench parts 122 are formed alternately along a circumference at almost the same pitches, are arranged tandem in the shaft direction and collectively formed in an unified body. The magnetic pole protruding parts 121 of one out of the gear-shaped rotor parts 120A, 120B and the trench parts 122 of the other one out of the gear-shaped rotor parts 120A, 120B are aligned in lines.  All of the magnetic pole protruding parts 121 of the respective gear-shaped rotor parts 120A, 120B have the same polarity, and the magnetic pole protruding parts 121 of the first gear-shaped rotor part 120A have different polarity from the magnetic pole protruding parts 121 of the second gear-shaped rotor part 120B. This magnet rotor 100 can be magnetized on the protruding parts 121 of the respective gear-shaped rotor parts 120A, 120B by right and left two poles magnetization (thrust magnitization). Only a boundary line part 123 turns to a dead area, and magnetization of low impedance and high magnetomotive force is enabled. Thereby a magnet rotor which has high energy product in spite of a small diameter can be realized.
