Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coating device capable of obtaining an excellent sheet in which thickness of a coated layer is uniform in the cross direction after coating treatment and difference of thickness and thinness is prevented and also capable of being continuously operated for a long period. SOLUTION: Coating liquid 11 is applied to a continuously traveling sheet 8 by a liquid-sticking roll 12 and thereafter coating liquid is weighed and regulated by a weighing instrument 9. The coating device is constituted by installing coaters 6 provided with the surface parts which are expanded by air pressure and brought into contact with the traveling sheet 8 on the uncoated surface side of the sheet 8.
