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 a covering process of covering a part of a surface of a bar coming in contact with a coating liquid with a fluorine-based resin; and a baking process of baking the fluorine-based resin covering the part of the surface of the bar at a temperature of 100 to 380° C.
