PURPOSE: To provide an apparatus for intermittently coating a substrate with a coating fluid, wherein the substrate can be coated with the coating fluid mostly suitably, intermittently, and easily upon a change in a coating pattern, a coating fluid, or the like. CONSTITUTION: In an apparatus for intermittently coating the surface of a substrate with a coating agent wherein a coating agent is introduced into a die for coating the surface of a substrate to be conveyed with a coating agent; the coating agent is temporarily held in a manifold, the fluid is ejected through an ejecting port open to the surface of the conveyed substrate through a feed passage having a flexible plate; and when the flexible plate is displaced in the direction going farther from the passage, a coating fluid intake space communicating with the passage is formed to temporarily stop the ejection of the coating agent onto the substrate, an apparatus for intermittently coating the surface of a substrate with a coating agent comprising attaching a threaded shaft fitted into a ball nut that is rotated by a servomotor to the flexible plate, and performing the displacement position control of the flexible plate by the movement of the threaded shaft in the axial direction by the rotation of the servomotor.
