PROBLEM TO BE SOLVED: To provide a permanent magnet type motor which requires no additional mold or jig tool by using components of the motor in common. SOLUTION: The motor includes a stator 9, a rotor shaft 1 and a rotor 3 having a permanent magnet 2 provided on a surface of the rotor shaft 1. A gap surrounded by the rotor shaft side of the permanent magnet 2 and the surface of the rotor shaft 1 is formed by forming the rotor shaft side in a cross section of the permanent magnet 2 in an approximately arc-shape and by making a curvature of the arc shape larger than a curvature of the rotor shaft 1, and an adhesive 13 is filled into the gap.
