PROBLEM TO BE SOLVED: To provide an applicator of a coating liquid which applies a coating liquid with a necessary minimum coating amount on the upper face of a plate such as a rectangular and flat glass plate, resin panel and the like without coating unevenness and without intrusion of the coating liquid into the rear face side. SOLUTION: The applicator of the coating liquid is composed by arranging a plurality of nozzles for supplying a coating liquid in parallel and in a constant pitch to the width direction perpendicular with the conveying direction of the glass plate, then connecting each of them with a tube respectively via an electromagnetic valve that stops freely to supply the coating liquid from the coating liquid tank to each nozzle respectively and arranging a needlelike needle part that discharges the coating liquid at each distal end portion of the needle part to the perpendicular direction to the glass plate. The film thickness on the glass surface is uniformalized by conducting the leveling in a conveying state of the glass plate and expanding the area of each belt-like application surface until the gap disappears mutually after applying the coating liquid so that each belt-like application surface becomes parallel with a distance of approximately a/4-a/30 wherein a is the width of each belt-like application surface immediately after the application formed on the upper surface from the leading edge to the rear edge of the glass plate by discharging the coating liquid from the needle part.
