A blower fan structure of an air conditioner includes a plurality of blades(110) disposed with a uniform interval with respect to a rotation center(P), wherein an inlet angle(alpha) of the blades is 29-31‹, an outlet angle(beta) of the blades is 1‹, and a ration between inner and outer diameters of the blades is 0.6-0.65. The number of the blades is 9.
