Abstract
A film-forming method is provided in which generation of an edge bead can be prevented even in a case where the thickness of a coating solution is large, and includes the steps of applying a coating solution onto a substrate to be treated such that thickness of the coating solution is 20 μm or more, placing the substrate into a heating space defined within an oven unit in which heating devices are provided in upper and lower portions of the heating space, and heating the substrate at a temperature-rising rate of 80 to 120° C./10 min so as to remove a solvent within the coating solution while keeping the substrate in a non-contact state with respect to the heating devices.
