Abstract
A coating film forming apparatus includes: a coating nozzle; a horizontal moving mechanism that relatively moves a substrate and the coating nozzle; a pressure regulating mechanism that regulates a pressure inside the coating nozzle; and a controller that changes an amount of the coating solution to be supplied from the coating nozzle, wherein the coating nozzle includes: a discharge port that is formed long in a direction perpendicular to a direction of the relative movement with respect to the substrate; and a storage chamber that communicates with the discharge port and stores the coating solution therein, and wherein while the coating solution is applied to the substrate, the pressure regulating mechanism is controlled according to a change in width of the substrate, to regulate the pressure inside the storage chamber to thereby change a discharge amount per unit time of the coating solution to be discharged.
