PURPOSE: An axial flow fan is provided to reduce fan noise while improving blowing performance of the axial flow fan by preventing a lamination area from being created in a negative pressure plane of a blade. CONSTITUTION: An axial flow fan(50) includes a hub(51) and a plurality of blades(52). The hub(51) has a cylindrical shape and is rotated by receiving driving force from a motor. The blades(52) are radially aligned around an outer peripheral portion of the hub(51). The blade(52) has a convex camber. When the axial flow fan(50) is driven by means of the motor, the blades(52) are rotated about a rotating shaft of the hub(51). Since the blade has the convex camber, an incident angle of air at a leading edge becomes enlarged.
