A CDV method in which a substrate having a surface to be deposited where the film is placed in a reaction chamber and a reactive gas introduced into the reaction chamber is excited by irradiation with flat light and scattered light to thereby deposit the film on the substate surface. The flat light is directed along the substrate surface in close proximity thereto, and the scattered light is directed to the substrate surface thereto.
