PROBLEM TO BE SOLVED: To easily provide an axial flow fan, at a low cost, capable of coping with humidity resistance, drop-resistance or the like at the time of mounting under a bad environment. SOLUTION: The axial flow fan is provided with a can of a cup shape with bottom shielding a rotation part and a fixed part. A stator of an electric motor and a control circuit part are disposed at an inner surface side of the can and a rotor of the electric motor and an impeller integrally formed therewith are disposed at an outer surface side of the can. The humidity resistance/drop- resistance effect against an energization part is obtained by shielding the stator of the electric motor and the control circuit part against an atmosphere.
