Zusammenfassung:	Provided is a propeller fan that can prevent deformation of the propeller fan while maintaining the basic performance thereof, such as the air blowing performance, efficiency, and noise performance. In a plastic propeller fan (1) including a hub (2) and a plurality of blades (3) integrally molded in a radial pattern on the outer circumference of the hub (2), assuming that the radial size of each blade (3) from the base to the outer peripheral edge (6) is 100, a ring member (10) that joins the plurality of blades (3) together is provided at a dimension position of 5 to 45 from the outer peripheral edge (6).
