    Abstract: A method for coating a top of a substrate with a coating solution, the method includes: supplying, before a solution film of the coating solution formed on the substrate dries, a solvent for the coating solution to a peripheral portion on the solution film of the coating solution on the substrate while rotating the substrate at a predetermined rotation speed to form a mixed layer of the coating solution and the solvent at the peripheral portion; and then, controlling a film thickness of the coating solution after drying by rotating the substrate at a rotation speed higher than the predetermined rotation speed to push the mixed layer to an outer peripheral side.
