PROBLEM TO BE SOLVED: To provide a cross flow fan capable of reducing noise by the vibration of a fluid and increasing air blowing performance. SOLUTION: This cross flow fan 1 comprises 34 to 36 sheets of vanes. The pitches (angles) of the vanes are at random. Where the maximum pitch (angle) is Pmax and the minimum pitch (angle) is Pmin, a difference between the maximum pitch and the minimum pitch is formed so that the relation of 1.0 (deg)≤Pmax-Pmin≤2.5 (deg) can be established.
