PROBLEM TO BE SOLVED: To provide a good electromagnetic wave shielding capability and enable realization of a light transmissive sharp image and easy manufacture, by printing a conductive ink to form a conductive layer on a plate surface of a transparent substrate. SOLUTION: Two transparent substrates 2A and 2B are bonded and integrated by an adhesive layer 4, and a conductive layer 3 is formed by pattern printing on the surface of the transparent substrate 2A on the side of the adhesive layer 4. Specifically, the transparent substrate 2A having the conductive layer 3 formed thereon in advance is used, and an adhesive film formed by mixing a cross-linking agent for thermal or optical curing into an ethylene copolymer such as EVA or the like and shaping the mixture into a sheet is provided between the transparent substrates 2A and 2B. After preliminary compression bonding is carried out by deaeration under a reduced pressure and with an increased humidity, the adhesive layer is cured and integrated by heating or light irradiation. By this process, an electromagnetic wave shielding light transmission window material can be easily manufactured. Thus, desired electromagnetic wave shielding property and light transmissiveness can be obtained by selecting the shape of pattern printing of the conductive layer. |
