PROBLEM TO BE SOLVED: To uniformly dry a coated film without changing physical properties such as viscosity of a coating liquid and the like and a kind of a solvent. SOLUTION: A drying zone 14 is provided just after coating, a wind which is not uniform in intensity and direction from outside the drying zone 14 is prevented from directly touching a surface of the coated film, and dry environment wherein an organic solvent evaporated from the surface of the coated film covers the surface of the coated surface, is generated. Then, under the dry environment, a regular dry wind of one direction flow flowing from one edge of a width direction of a web 12 to the other edge is generated in the dry zone 14.
