TRANSPARENT MEMBER FOR SHIELDING ELECTROMAGNETIC WAVES AND METHOD OF PRODUCING THE SAME

摘要

The invention provode a transparent member for use as a shield against electromagnetic waves characterized in that an electrically conductive reticular pattern is provided on a substrate (1) by forming a thin-film layer (2) of copper or an alloy thereof on the substrate by physical thin film forming means and forming a copper thick-film layer (4) on the thin-film layer by plating means so as to give the member a total transmittance of at least 50%, the reticular pattern having an electric resistivity of up to 200 m OMEGA / &squ& . <IMAGE>
