ABSTRACT:
A method of producing a die coater structured with at least two bars so as to form a pocket section to extend a coating liquid in a coating width direction, a coating liquid supply port to supply a coating liquid to the pocket section, and a slit section to discharge a coating liquid from the pocket section to a material to be coated, wherein at least a part of a surface of the two bars coming in contact with a coating liquid is covered with a fluorine-based resin, the method comprises steps of: a preheating step of conducting a preheating process for a bar with a preheating temperature higher than a baking temperature in a baking process in a covering step of a fluorine-based resin; a grinding step of grinding the bar subjected to the preliminary heating process; and the covering process of covering a part of a surface of the bar with a fluorine-based resin so as to form a covered section, wherein the surface of the bar was subjected to the grinding step and comes in contact with a coating liquid.
