    Abstract: PROBLEM TO BE SOLVED: To provide a coating method and a coater for applying a coating liquid having a viscosity of of ≤10 cp in a wet amount of application of ≤10 cc/m
    2 coating, at increased speed.
    SOLUTION: A die 14 is formed with a lip provided on the downstream side in a travel direction of a web so as to project more to the web side than the lip provided on an upstream side and is formed with a rugged part consisting of a plurality of ruggedness on a land at the top end of the lip on the upstream side. The depth of the ruggedness of the rugged part is ≥5 to ≤500 μm and the pitch of the ruggedness is 50 to ≤500 μm. The application is performed by using the die subjected to matting of the land or ceramic thermal spraying or engraving.

    Abstract: PROBLEM TO BE SOLVED: To obtain a large-sized pellicle containing a very small quantity of foreign matter inexpensively by establishing a technique for maintaining/controlling a die of a die coater. SOLUTION: The tip of the die is immersed in or contacted with a coating liquid stored in a vessel or the like. When the die is used, the die is raised upward slowly so that a droplet of the coating liquid is not made to remain at the tip of the die by the surface tension of the coating liquid. Then, the coating liquid is discharged/applied onto a substrate. It is preferable that the die is always immersed in or contacted with the coating liquid except the time when the coating liquid is applied and the coating liquid made to pass through a filter is discharged continuously or intermittently from the tip of the die and the die in the coating liquid is subjected to ultrasonic cleaning at the same time when the die is immersed in or contacted with the coating liquid.
