To apply a liquid material at a high speed while keeping a coating amount constant.
In a coating apparatus for applying a coating liquid 19 on the surface of a work 3, a controller controls so as to repeat a discharge and moving action that the work 3 is arranged in a previously fixed adjacent position to form a prescribed interval between the work 3 and a nozzle 16 by moving a stage holding the work 3, the coating liquid 19 is discharged through the nozzle 16 to be in contact with the surface of the work 3 and the stage holding the work 3 is moved in the vertical direction to the discharge direction of the coating liquid. The liquid standing outside the nozzle 16 is decreased by moving the work 3 to the vertical direction to the discharge direction, the fixed quantity of the coating liquid 19 is applied constantly and also the speed is increased by a portion needless for the conventional upward and downward movement of the work 3.
