Patent abstract
Provided is an axial fan including a plurality of blades configured to produce an air current flowing from an inlet side to an outlet side, in which: the blade includes a curved portion rising toward the inlet side along an outer peripheral edge of the blade; a starting position of the curved portion delineates a convex curve protruding radially outward on the blade as viewed from the inlet side; and letting a total length of the convex curve be X, a length Y from an end of the convex curve on a front edge of the blade to a vertex of the convex curve satisfies a relationship of 0<Y≤0.6X as viewed from the inlet side.
