In the prior art, as the amount of a fluid discharged by a fluid discharge device becomes more minute, defects occur in which the fluid does not fill in a mask even when discharged. In order for the fluid to fill in a work piece, air in a discharge portion of the work piece must be replaced by the fluid, and by removing the air from the work piece in advance according to the present invention, the discharged fluid fills in the work piece. In the present invention, a fluid discharge device is used in which a suction port for suctioning the air in a mask on a work piece and a discharge nozzle for discharging the fluid are formed at one end of the discharge head.
