PURPOSE: A turbo fan of an air conditioner is provided to improve efficiency by minimizing loss caused through vortex and to prevent noise by forming efficient flowing of air. CONSTITUTION: A turbo fan for an air conditioner comprises an impeller plate(50) having a circular shape; plural blades(60) vertically formed along a circumference of the impeller plate; a shroud(70) letting air by minimizing pressure loss by being connected to an end portion of the blade; a hub(52) receiving rotational power by being engaged with a rotational shaft of a driving motor on the impeller plate; and a front face contacting to the shroud by being installed on the blade. The hub is formed by injecting mold with the impeller plate. The impeller plate is formed as a dome shape toward an inlet port of a floor face of the impeller plate. Thereby, the turbo fan for the air conditioner prevents noise by equally forming flowing of the air.
