Provided is a propeller fan (1) capable of achieving lower noise by suppressing a leakage flow of an air current, and also achieving higher efficiency by increasing the rate of air to be blown. The propeller fan (1) includes a boss (2) including a rotation axis (O), a plurality of blades (3) formed on an outer periphery of the boss (2), and a bellmouth (9) arranged so as to surround the plurality of blades (3) at a trailing edge side of each of the blades (3). Each blade (3) has a bending portion (13) that bulges toward an upstream side of the air current in a cross-sectional shape in a radial direction, and a bend of the bending portion of the blade at an inner side of the bellmouth is set to be gentler than a bend of the bending portion of the blade at an outer side of the bellmouth.
