Abstract:
There is provided an impeller for an axial flow fan, which includes a plurality of blades arranged in a circumferential direction. In each of the blades, with respect to a center point of a chord length of the blade, a leading edge side shape of the blade and a trailing edge side shape of the blade are line-symmetric, and a shape of the blade at one face side is different from a shape of the blade at the other face side.
