Claim:
A coating applicator comprising: a turntable retaining a coating object thereon; a rotating device for rotating the turntable; a coating nozzle for applying a coating solution to a surface of the coating object by discharging the coating solution from a nozzle orifice at a flattened end thereof to the coating object retained on the turntable; a transfer device for moving the coating nozzle relative to the coating object in a direction intersecting a rotational direction of the coating object; and a rotation control unit for controlling the rotation of the coating nozzle, wherein the coating nozzle including the nozzle orifice is formed with an angled notch at only one side of the coating nozzle, forming a flat plane intersecting with the flattened end of the coating nozzle and the rotation control unit controls the rotation of the coating nozzle in a manner to position the angled notch of the coating nozzle upstream from a position to feed the coating solution to the coating object being rotated, and wherein the coating nozzle is formed with a chamfer that is smaller in width than the angled notch and extends along an outside circumference of the coating nozzle end formed with the angled notch.
