PURPOSE:To obtain a transparent window plate for shielding radio wave, by forming a conductive metallic thin film on the whole surface of a plate of a non conductive transparent material and by forming an earthing surface by applying conductive paint to the peripheral part of the metallic film. CONSTITUTION:A conductive metallic thin film 2 is formed on the whole surface of a transparent insulating plate 1 such as plastics and glass by a vacuum deposition, sputtering and other processes. The electrically conductive paint 3 incorporated with metallic powder and carbon powder etc. is applied at its peripheral part to form an earthing surface. By this way, a transparent window plate for shielding radio wave is obtained. |
