PURPOSE:To uniformly coat a paint to a base material at a uniform film thickness by forming a die of a coating device into a floating type for which a balance weight is used and maintaining a specified spacing between the die and the base material by a spacing holding means. CONSTITUTION:The die 4 of the device for coating the paint on the sheet-shaped base material on a conveying roller is made of the floating type die 4 for which the balance weight 10 is used. The spacing holding means 11 for maintaining the specified spacing between the surface of the base material 1 and a slit- shaped discharge port 3 by contacting the surface of the material 1 is provided on both sides of the surface of the die 4 on the port 3 side in the transverse direction of the material 1. The die can be moved with light force and the position of the die follows up the uneven thickness which exists in the base material if the weights of the die and the balance weight are balanced in the above-mentioned manner. The coating to a uniform thickness is thus continuously executed.
