Claim Text:
1. A coating method for forming a thin film of a coating solution on a substrate, comprising: a coating solution supply step of supplying the coating solution onto the substrate from a coating solution feed mechanism having an arrangement of inkjet nozzles; a smoothing step of smoothing a thin film surface of the coating solution by jetting a gas from a gas jet mechanism to the coating solution supplied onto the substrate; and a solvent supply step of supplying a solvent of the coating solution from a solvent feed mechanism onto the substrate before the coating solution supply step; wherein the coating solution feed mechanism moves in a direction of movement while supplying the coating solution; the gas jet mechanism jets the gas obliquely forward in the direction of movement while moving integrally with the coating solution feed mechanism, while disposed rearward of the coating solution feed mechanism with respect to the direction of movement; and the solvent feed mechanism supplies the solvent only obliquely rearward in the direction of movement while moving integrally with the coating solution feed mechanism, the solvent feed mechanism being disposed forward of the coating solution feed mechanism with respect to the direction of movement; whereby the coating solution feed mechanism supplies the coating solution onto a thin film of the solvent.
