PROBLEM TO BE SOLVED: To provide a light transmitting window material having shielding property against electromagnetic waves which is excellent in the shielding property against electromagnetic waves and has high antireflection effect and excellent transparency and visibility so that sharp images can be obtained. SOLUTION: The light transmitting window material 1 having shielding property against electromagnetic waves is obtained by laminating and integrating an antireflection film 3, a film 10' having shielding property against electromagnetic waves with a cohesive film, a transparent substrate 2, and a near IR cut film 5 having an intermediate film 4B for adhesion and a pressure sensitive adhesive 4C, and then covering the peripheral edge part with a conductive cohesive tape 7. A conductive cohesive tape 8 is stuck to the peripheral edge of the film 10' having shielding property against electromagnetic waves with the cohesive film and to the peripheral edge of the transparent substrate 2. The film 10' is produced by adhering a conductive foil 11 to a transparent base film 13 with a transparent adhesive 14, pattern etching, forming a light absorbing layer 12 and subjecting the surface of the light absorbing layer 12 to roughening treatment for antireflection and non-gloss treatment. The surface subjected to the antireflection and non-gloss treatment is filled with the transparent pressure sensitive adhesive 15. |
