Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coated film which restrains the generation of a coating streak in the longitudinal direction, in the coated film manufactured by a rotary wire bar, and a coating device and a manufacturing method of a coated film. SOLUTION: This coated film 16a with an adjusted coat thickness is manufactured by first, applying an excess amount of coating liquid 17 to the surface of a film 16 running continuously at a speed of 100 m/min or more and then, pressing a wire bar 22 formed by winding a wire 22b with 20 to 200 μm diameter around the outer peripheral surface of a columnar bar body 22a, to the surface of the film 16. In addition, the wire bar 22 is formed so as to have such a relationship established that the value of the diameter (μm) of the wire 22b/a gap (μm) between the wound wires 22b is higher than the value of 0.09 × application rate -6 (m/min). Thus, the visually confirmed coating steak extending in the longer direction is eliminated. COPYRIGHT: (C)2008,JPO&INPIT
