A propeller fan with two blades includes a blade and a blade, and a connection portion connecting the blades together. Each blade has a peripheral edge portion extending in an arc having a diameter D with a center axis as a center thereof, a front edge portion arranged on a forward side in a rotational direction, a rear edge portion arranged on an opposite side in the rotational direction, and a leading blade edge portion connecting the front edge portion and the peripheral edge portion. A plane which includes each intersection between the rear edge portion and the peripheral edge portion and is perpendicular to the center axis is defined as γ. When the propeller fan is viewed in a direction parallel to a plane including the leading blade edge portions and the center axis, a distance H between plane γ and a connected portion between the front edge portion of the blade and the rear edge portion of the blade, on a line of the center axis, satisfies 0.028≦H/D≦0.056. With such a structure, a propeller fan, a molding die, and a fluid feeder which make a significant contribution in terms of energy-saving properties and resource-saving design can be provided.
