An air spindle to minimize the vibration and the noise is provided to make a rotor processed easily and to reduce an error. An air spindle comprises a housing(100) and a rotor(200). The air flows in the housing. The rotor is connected to a rotation bearing(211) of the housing inside and rotates by the air flowing in at the high speed. An inclined supply path is formed at the housing to be inclined to a rotary shaft of the rotor. The rotor rotates since the air is supplied through the inclined supply path to the to a rolling friction ball.
