Abstract: A centrifugal fan and an air conditioner using the same are provided. A gurney flap having a rectangular plate or a S-shaped, twisted gurney flap may be formed in a tip of a blade provided in or on a hub of the centrifugal fan, so that noise may be effectively reduced, and efficiency increased. Further, the blade with the gurney flap may be easily formed integrally with the hub, enhancing productivity.
