A reflecting film has at least a transparent polymer film and a thin silver layer applied on the transparent polymer film to reflect light entered from a side of the transparent polymer film. The reflecting film retains a reflectance of at least 90% to visible light even after the reflector is exposed for 300 hours at a reflecting film temperature of 100.degree. C. and an exposure intensity of 500 mW/cm.sup.2 to artificial sunlight from which light of 390 nm and shorter in wavelength has been eliminated. For fabricating the reflecting film, a surface of the transparent polymer film is preferably treated with a metal-containing plasma, then the thin-silver layer is deposited on the treated surface. A reflector making use of the reflecting film is also disclosed.

[ What is claimed is:] [14.] A reflecting film having at least a transparent polymer film and a thin silver layer applied on said transparent polymer film to reflect light entered from a side of said transparent polymer film, wherein said reflecting film retains a reflectance of at least 90% to visible light even after said reflecting film is exposed for 300 hours at a temperature of 100.degree. C. and an exposure intensity of 500 mW/cm.sup.2 to artificial sunlight from which light of 390 nm and shorter in wavelength has been eliminated, and wherein said transparent polymer film is subjected on one side thereof to surface treatment with a metal-containing plasma to provide a treated surface and said thin silver layer is then formed on said treated surface.
