ABSTRACT:
The production process of an electromagnetic wave shielding material of the present invention comprises screen printing a conductive paste containing conductive particles, binder and solvent in a geometrical pattern on the surface of a transparent porous layer of a transparent resin substrate provided with the transparent porous layer, the porous layer containing as a main component thereof at least one type selected from the group consisting of an oxide ceramic, a non-oxide ceramic and a metal, followed by forming a conductive portion in a geometrical pattern on the surface of the transparent porous layer by heat treatment. An electromagnetic wave shielding material produced according to this production process has high electromagnetic wave shielding effects and superior transparency and visibility.
