Disclosed herein are a turbo fan, which is capable of implementing high efficiency of ventilation and reducing noise by providing a bended portion being bended in a reverse direction against a rotational direction of a wing between a leading edge and a tailing edge thereof to reattach an air separation generated at a negative pressure surface of the wing, and an air conditioner having the same. The air conditioner includes the turbo fan, wherein the turbo fan includes a main plate having a disc shape and on which a rotational shaft is mounted, a side plate provided to be separated from the main plate along an axial direction of the rotational shaft and having a ring shape in which an opening is provided at a center portion of the side plate, and a wing fixed between the main plate and the side plate and provided in plural numbers along a circumferential direction of the main plate, and wherein a bended portion, which is bended in a reverse direction against a rotational direction of the wing, is provided at the wing between a portion of a leading edge of the wing coming in contact with the side plate and a tailing edge of the wing.
