Patent ID: 8631760

Claim:
A coating tool comprising a coating head composed of a plurality of head members, wherein: a grooved slot is formed between two interior surfaces which face each other in the plurality of head members, extends in the longitudinal direction of the coating head, and is open into the tip of the coating head, and the grooved slot has a flow-rate control area and a flow rate stabilizing area; coating liquid flows through the slot, and is discharged from the tip of the coating head; a convexity which rises toward one side surface of the two interior surfaces, can be formed convexly on the other side surface of the two interior surfaces by elastically deforming a portion on the other side surface; a concavity which sinks away from the one side surface, can be formed concavely below the other side surface by elastically deforming a portion on the other side surface; and an internal flow-rate control mechanism is provided to control the flow-rate of the coating liquid in the slot by adjusting the above convexity and/or concavity, wherein the coating liquid flows from a pocket in which the coating liquid is filled and from which the slot extends to the tip side, the pocket being positioned close to the flow-rate control area, the flow-rate control area is positioned at a rear side of the convexity and/or concavity, and the flow-rate stabilizing area extends toward the tip side from the flow-rate control area.
