Provided is a coating tool for forming a film having uniform thickness on a target by controlling precisely a flow-rate of a coating liquid, even if its viscosity is high. In the coating tool, a coating head 1 includes a pair of head members 10 and 20; a slot 3 is formed between a pair of interior surfaces 11 and 21, facing each other, of the head members 10 and 20; and a coating liquid flows through the slot 3 and is discharged from the tip of the coating head 1. An internal flow-rate control mechanism 60 is provided to control the flow-rate of the coating liquid in the slot 3 by adjusting a convexity and/or a concavity.
