Beschreibung
Zusammenfassung:	A coated film manufacturing method and a coating machine are provided which can prevent deformation of a die coater due to evaporation of a coating liquid and prevent surface deficiency occurring when starting the coating. A coating machine is prepared which includes a die coater having a manifold, a slot communicating with the manifold, and a lip face formed at an end of the slot, a heat-insulating plate being disposed in a region below the lip face of the die coater and having a tapered top end portion, and a depressurizing chamber being disposed upstream in a web conveying direction from the die coater. The coating machine is made to stand by at a position for forming a clearance greater than a predetermined clearance between the coating machine and the web at the time of coating while flowing the coating liquid from the die coater.
