Abstract

An axial-flow fan according to the present disclosure can increase the amount of the airflow and simultaneously reduce the noise level. A plurality of stationary blades 11A to 11D are curved, in a convex manner, toward a rotating direction of an impeller. The plurality of stationary blades 11A to 11D are generally inclined so that discharge-side edge portions 11d thereof are located more forward than suction-side edge portions 11c thereof in the rotating direction. An inclination angle θ4 of each of the plurality of stationary blades 11A to 11D in the vicinity of the external end portion 11a is larger than the inclination angle θ3 in the vicinity of the internal end portion 11b. The inclination angle is gradually changed from the vicinity of the external end portion 11a toward the vicinity of the internal end portion 11b.
