To suppress drying unevenness and to efficiently dry a coating film formed by applying various kinds of liquid compositions on a continuously traveling flexible belt.

A dryer 18 for condensing and recovering a solvent in a coating liquid directly after the various kinds of liquid compositions are applied on the continuously traveling flexible belt 12 by a coating means 16 is arranged in an apparatus for drying the coating film. A condensation plate 20 is arranged in parallel to the flexible belt 12 with a certain interval in the dryer 18. The condensation plate is inclined upward by ≥5° toward the traveling direction of the flexible belt. The traveling speed of the flexible belt is controlled so that the flexible belt reaches the dryer within 30 seconds after the application of the coating liquid by the coating means is completed.
