PROBLEM TO BE SOLVED: To provide a web-form adhesive film excellent in the ability to shield electromagnetic waves generated from the front surface of a display, infrared shielding properties, transparency, invisibility and good adhesiveness. SOLUTION: A geometrical figure having a degree of openings of 80% or above is formed on the conductive metal of a plastic film with the conductive metal by an etching process. An adhesive composition having a refractive index in the range of 1.45-1.60 is applied to part or the entire of the surface of the base material containing the geometrical figure, and a resin composition having an infrared absorptivity of 50% or above at a wavelength of 900-1,100 nm on the coated surface or the opposite surface, By continuously performing the steps from film delivery to film winding, a web-form electronic wave-shielding adhesive film is obtained. |
