Abstract: A centrifugal fan comprises a rotor that has a rotor yoke, an impeller that has a blade and is coupled to the outer periphery of the rotor yoke, a motor that rotates the rotor and a casing that has a suction opening and a discharge opening, and houses the rotor, the impeller, and the motor. The impeller rotating together with the rotor discharges air sucked in through the suction opening to the outside of the casing through the discharge opening. An inner periphery part of the blade on the rotor yoke side extends to the inner periphery side, in such a manner as to overlap with an outer peripheral surface of the rotor yoke in the axial direction of the motor.
