Abstract

An impeller applied to a centrifugal fan includes a base plate, a hub and a plurality of blades. The hub is connected to the base plate. The blades are disposed around the base plate with respect to the hub as a center. The blades are the backward leaning structures and each has at least one inversely inflective portion adjacent to one end thereof. A centrifugal fan including the impeller is also disclosed.
