Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus for uniformly applying a coating material, a resin, a liquid chemical, and the like, which fall like a curtain in a process of applying the coating material, the resin, the liquid chemical, and the like, onto a steel sheet, a galvanized steel sheet, and the like, and to provide a coating method using the apparatus. SOLUTION: The apparatus for uniformizing steel sheet coating is provided with a nozzle for discharging gas in a step in which the coating material or liquid chemical is caused to fall from above to the steel sheet transported horizontally. The nozzle is disposed upstream in the transport direction of the steel sheet from a position where the coating material or liquid chemical falling like the curtain collides with the steel sheet, wherein the nozzle has a discharge port for discharging the gas in the directions opposite to and parallel to the transport direction of the steel sheet, and the discharge divergence angle (θ) in the vertical direction of the gas discharged from the discharge port of the nozzle is
