Abstract
A propeller fan according to the present disclosure includes a rotation shaft and a blade rotating around the rotation shaft. At the same position in an axial direction of the rotation shaft, a first locus connecting a leading edge of the blade and an outer peripheral end of the blade is tilted with respect to a second locus connecting a center of the rotation shaft and the leading edge so that the outer peripheral end side is inclined toward a trailing side. Alternatively, a third locus connecting a root of the blade and the outer peripheral end of the blade is tilted with respect to a fourth locus connecting a center of the rotation shaft and the root so that the outer peripheral end side is inclined toward the trailing side.
