A propeller fan, comprising: a rotational axis serving as a center of rotation; and a plurality of blades provided around the rotational axis, a bell mouth being arranged outside in an outer radial direction of the plurality of blades, wherein each of the plurality of blades is formed by a trailing edge portion formed on the rear relative to a rotation direction, wherein the trailing edge portion has a curvature with an inflection point, a leading edge portion formed on the front relative to the rotation direction, a blade tip portion formed from a tip portion in an outer radial direction of the trailing edge portion toward a tip portion in an outer radial direction of the leading edge portion, wherein the trailing edge portion which has been rotationally projected on a plane passing through the rotational axis is formed from the rotational axis toward the blade tip portion so as to bend from the suction side to the discharge side with a first convex curvature (α), and further is formed so as to bend with a second convex curvature (β), wherein a radius of the second convex curvature (β) is smaller than a radius of the first convex curvature (α), and wherein the inflection point is interposed between the first convex curvature (α) and the second convex curvature (β), and wherein the trailing edge portion which has been rotationally projected on a plane vertical to the rotational axis is formed to be convex in a reverse rotation direction from the rotational axis toward the blade tip portion, and is formed linearly or to be convex in the rotation direction with the inflection point interposed. a rotational axis serving as a center of rotation; and a plurality of blades provided around the rotational axis, a bell mouth being arranged outside in an outer radial direction of the plurality of blades, wherein each of the plurality of blades is formed by a trailing edge portion formed on the rear relative to a rotation direction, wherein the trailing edge portion has a curvature with an inflection point, a leading edge portion formed on the front relative to the rotation direction, a blade tip portion formed from a tip portion in an outer radial direction of the trailing edge portion toward a tip portion in an outer radial direction of the leading edge portion, wherein the trailing edge portion which has been rotationally projected on a plane passing through the rotational axis is formed from the rotational axis toward the blade tip portion so as to bend from the suction side to the discharge side with a first convex curvature (α), and further is formed so as to bend with a second convex curvature (β), wherein a radius of the second convex curvature (β) is smaller than a radius of the first convex curvature (α), and wherein the inflection point is interposed between the first convex curvature (α) and the second convex curvature (β), and wherein the trailing edge portion which has been rotationally projected on a plane vertical to the rotational axis is formed to be convex in a reverse rotation direction from the rotational axis toward the blade tip portion, and is formed linearly or to be convex in the rotation direction with the inflection point interposed.
