The present invention aims to provide a transparent electromagnetic wave shield member, which is free from a moirè phenomenon which could not be solved by the prior art, and in which an excellent electromagnetic wave shielding properties and a sufficient total light transmittance based on an appropriate network structure are compatible, and a method for manufacturing the same.
The transparent electromagnetic wave shield member of the present invention is a transparent electromagnetic wave shield member in which a metal layer of an electroconductive metal network structure having a geometrical shape is formed on a transparent substrate, and which is characterized in that a spacing of said network structure is 200 μm or less, an opening ratio of the network structure is 84% or more, and in addition, a thickness of the electroconductive metal layer is 2 μm or less.
Furthermore, the method for manufacturing such transparent electromagnetic wave shield member is a method for manufacturing a transparent electromagnetic wave shield member in which a metal layer of a network structure having a geometrical shape is formed on a transparent substrate, which is characterized in that a metal layer of a thickness of 2 μm or less is provided on a transparent substrate and the metal layer is removed by laser abrasion to form a metal layer of a network structure having a spacing of the network structure of 200 μm or less, and in addition, an opening ratio of the network structure of 84% or more.
