Title:
ELECTROMAGNETIC WAVE-SHIELDING SHEET
Document Type and Number:
WIPO Patent Application WO/2004/016058
Kind Code:
A1
Abstract:
An electromagnetic wave-shielding sheet (1) comprises a transparent base member and a metal layer that is laid over one face of the transparent base member. The metal layer has a mesh-like mesh portion (103), a mesh-like mesh outer-periphery portion (104) surrounding the mesh portion (103), and a grounding frame portion (101) surrounding the mesh outer- periphery portion (104). The width of a line forming meshes of the mesh outer- periphery portion (104) is gradually expanded in width from the mesh portion (103) toward the grounding frame portion (101). In the entire steps from the production to assembly of the electromagnetic wave-shielding sheet (1), bending or wire breakage is not likely to occur in the sheet, and therefore the sheet has an excellent aptitude for handling.
