PROBLEM TO BE SOLVED: To provide a transparent infrared ray cut-off film which can be manufactured at low costs, where metallic sheen is suppressed, and good electromagnetic wave transmission is exhibited even if a tin-containing indium oxide (ITO) is used. SOLUTION: A conductive coating composed of ITO powders and a resin is applied to the surface of a base film 1 for forming an infrared ray cut-off layer 3. A hard coated layer 2 is formed on the surface of the infrared ray cut-off layer 3, and a self-adhering layer 4 is formed on the back side of the base film 1. A mixing ratio of the ITO powder and the resin of the infrared ray cut-off layer 3 is 90/10-60/40 in weight ratio, which improves transparency. |
