Axial flow fan and air-conditioning apparatus having axial flow fan

An axial flow fan comprising a plurality of blades and being configured to rotate about a rotation axis of the blades to convey a fluid,

• the plurality of blades each having a leading edge at a leading side in a rotational direction, a trailing edge at a trailing side in the rotational direction, and an outer peripheral edge connecting the leading edge and the trailing edge,
• the leading edge of one of the plurality of blades and the trailing edge of another blade adjacent to the leading edge of the blade in the rotational direction being connected by a plate-shaped connection portion,
• the plurality of blades each having at least one plate-shaped reinforcement rib extending from a periphery of the rotation axis toward the outer peripheral edge of the blade,
• the reinforcement ribs being provided radially about the rotation axis, or being convex toward the leading edges.
