description An axial fan includes: an impeller including a rotating part, and a blade part connected to the rotating part; a bellmouth including a flat part orthogonal to an extension direction of a rotation axis of the rotating part; a rising part rising from the flat part; and an opening along which the rising part extends, the impeller being located in the opening, the rising part surrounding the impeller, the bellmouth including a plurality of grooves located at a surface of the bellmouth, the surface of the bellmouth being connected to an inner surface of the rising part, the inner surface of the rising part facing the blade part of the impeller, the plurality of grooves being located in at least a corner portion connecting the flat part and the rising part, the plurality of grooves extending in a direction crossing the flat part.
