Abstract: A motor-integrated fan sucks air from a suction port and blows out the sucked air from a blow-out port. The motor-integrated fan includes a shaft part that is provided at a center of a rotational axis; a rotation part that is rotated about the shaft part; an outer peripheral part that is provided on an outer periphery of the shaft part; a motor that rotates the rotation part; a heat generating part that generates heat due to an operation of the motor; and a cooling unit that cools the heat generating part with cooling air. The cooling unit includes an air intake port that takes the cooling air in, an air discharge port that discharges the cooling air, and a cooling flow channel that leads to the air discharge port from the air intake port via the heat generating part.
