PROBLEM TO BE SOLVED: To provide a method and apparatus for drying a coating film, wherein the coating film is uniformly dried by setting the temperature of a supporting body to be lower than the temperature of the coating film surface in the case of drying the coating film surface just after coating, so as to eliminate the effect of the supporting body in the initial drying the coating film. SOLUTION: In the method of drying the coating film formed by applying the coating liquid containing an organic solvent on the travelling long-sized supporting body 12, the temperature Tb of the long-sized supporting body 12 before coating is controlled to be≥2°C lower than the temperature Tc of the coating liquid and the wind velocity in the vicinity of the coating film after coating is controlled to be≤0.5 m/sec.
