Claim 8:
9. An air-conditioning apparatus comprising:
an outdoor unit; and
an indoor unit connected to the outdoor unit by a refrigerant pipe,
wherein the outdoor unit comprises:
an electric motor including a stator and a rotor that is rotatable relative to the stator, the rotor including
a rotor core made of magnetic material,
a plurality of permanent magnets attached to the rotor core such that the permanent magnets are spaced from each other in a circumferential direction of the rotor core and magnetic poles of the permanent magnets that face an outer peripheral side of the rotor core in a radius direction of the rotor core have the same magnetic polarity, and
a shaft made of magnetic material, and provided to extend through a central part of the rotor core in an axial direction of the rotor core, the shaft being magnetized by part of magnetic fluxes generated from the permanent magnets;

a fan provided on the shaft;
a fastening member made of magnetic material, and configured to fasten the fan to the shaft;
a heat exchanger to which air is sent by rotation of the fan; and
a housing that houses the electric motor, the fan, the fastening member, and the heat exchanger.
