COATING TOOL, COATING DEVICE AND COATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a coating tool capable of quickly discharging air bubbles accumulated in a coating tool.SOLUTION: A coating tool of the invention comprises: a first supply port 31 to which a coating liquid is supplied; a first manifold 11 connected to the first supply port 31; a discharge slit 22 to which the coating liquid is discharged; a second manifold 12 connected to the discharge slit 22; and a connection drawing channel 21 for connecting the first manifold 11 and second manifold 12. A first discharge port 41 for discharging air bubbles accumulated in the first manifold 11 to outside, is connected to the first manifold 11, and a second supply port 32 to which the coating liquid is supplied, and a second discharge port 42 for discharging air bubbles accumulated in the second manifold 12 to outside, are connected to the second manifold 12.SELECTED DRAWING: Figure 1
