| description | PROBLEM TO BE SOLVED: To provide a curtain coating method and a curtain coating apparatus by which quality of a coated film can be favorably held in the curtain coating apparatus where a curtain-shaped liquid film 2 is produced by a liquid film production apparatus 3 arranged above a continuously running metallic band 1 and the produced liquid film 2 is made to freely drop on the metallic band to apply the liquid film on a metallic film surface. SOLUTION: In the curtain coating method and the curtain coating apparatus, a gas discharge nozzle 4 is provided at an upstream side from a collision point 6 of the liquid film 2 to the metallic band 1, the nozzle has one gas discharge port or a plurality of gas discharge ports 5 for discharging gas in an upstream side direction onto whole width direction of the metallic band 1, an angle θ made by a width direction 12 of the liquid film and a width direction 11 of the metallic band (an width direction angle θ of the liquid film) is changed corresponding to width of the metallic band 1 and an angle α made by an arranging direction 13 of the gas discharge ports and the width direction 11 of the metallic band (an arranging direction angle α of the gas discharge ports) is changed corresponding to change of width direction angle θ of the liquid film.
