TRANSPARENT MEMBERS FOR USE AS SHIELDS AGAINST ELECTROMAGNETIC WAVES AND PROCESS FOR PRODUCING THE SAME

摘要

A transparent member for shielding electromagnetic waves characterized in that an electrically conducting mesh pattern is formed on a substrate by laminating in order a thin film layer of copper or an alloy thereof by a physical thin film forming means and a thick film layer of copper by a plating means, so that the total light transmittance is not smaller than 50 % and that the elctric resistance of the electrically conducting pattern is not larger than 200 m.OMEGA./.
