A permanent magnet motor includes a stator, and a rotor having a rotor core disposed opposing an inner side of the stator across an air gap, a permanent magnet disposed in a circumferential direction of the rotor core, and a field pole of the rotor core in which the permanent magnet is disposed, wherein the field pole has a radius smaller than an arc centered on a shaft attached to an inner side of the rotor, a multiple of a slit whose longitudinal axial direction is a radial direction of the rotor core are formed in the field pole, and an interval between a first central line positioned between a multiple of the slit and a second central line positioned between a neighboring multiple of the slit is enlarged as the first central line and the second central line head toward an outer peripheral side of the rotor core.
