Abstract
A thin film forming method includes: attaching a mixture of a dielectric material and a fluorocarbon resin as a first layer on a substrate; and thereafter attaching only a dielectric material as a second layer on the first layer to form a two-layer thin film on the substrate. The method is capable of manufacturing a thin film whose production is easy and costs low, whose substances attached by vapor deposition or the like do not easily suffer cracking, peeling, breakage, and so on, and in which a low refractive index is achieved in a wide band by freely controlling its packing ratio.
