Propeller fan

This propeller fan is provided with a hub (11) having a side surface around a center axis (O), and with a plurality of blades (12) provided to the side surface of the hub. Inner peripheral blades extending from the side surface of the hub toward the outer edge side are formed on the respective inner peripheral sections of the plurality of blades at positions on the positive pressure surfaces (12p) of blade surface sections (12c). The inner peripheral blades protrude from the positive pressure surfaces of the blade surface sections toward the positive pressure side (P) and include a plurality of blade elements arranged side-by-side in the rotational direction (R) of the blades. A first blade element (15a) disposed on the front edge side in the rotational direction of the blades among the plurality of blade elements is formed so that, if the vertex of the first blade element protruding from the positive pressure surface is A, the distance from the center axis to the vertex A is r, and a point located at the front edge of the first blade element in the rotational direction at the distance r from the center axis is B, the blade angle (θ) formed between a direction along the blade chord of the first blade element, which extends in the direction connecting the vertex A and the point B, and a plane perpendicular to the center axis is greater than or equal to a predetermined first angle and smaller than or equal to a second angle greater than the first angle.
