Abstract

A cross flow fan and an air conditioner including the cross flow fan, where the cross flow fan includes a fixing member (120), and a plurality of blades (110) fixed to an upper surface of the fixing member and spaced apart from each other in a circumferential direction. One or more of the blades (110) include a protrusion (113) protruding in a downward direction from a surface of the blade.
