PROBLEM TO BE SOLVED: To enhance coating accuracy, and to be widely applicable to various coating liquids, by uniformizing inner pressure of a manifold from the initial stage of coating.SOLUTION: A coating tool 1 is provided for coating the coating liquid on a coating object via a manifold 4 formed between mutual adjacent head members 2 by adjacently arranging a plurality of head members 2 and a slit 3 opened toward the tip side of the head members 2. The manifold 4 extends in the extension direction L of the head members 2, and the inside of the manifold 4 is provided with a shaft body 15 extending in the extension direction L and rotatably journaled by the head members 2 and a supply port 16 for supplying the coating liquid to the manifold 4, and an outer peripheral surface of the shaft body 15 is provided with a screw part 20 for gradually spirally twisting toward the axis O periphery for turning to the axis O direction, and the shaft body 15 is rotated around the axis O to the head member 2, so that the screw part 20 can feed liquid in the direction for separating the coating liquid in the extension direction L from the supply port 16. |
