Title:
ELECTROMAGNETIC SHIELDING SHEET
Document Type and Number:
WIPO Patent Application WO/2011/010697
Kind Code:
A1
Abstract:
Disclosed is an electromagnetic shielding sheet which has less increase in the thickness of a base after the formation of a metal coating film when compared with conventional electromagnetic shielding sheets, and which has excellent electromagnetic wave shielding properties with a small amount of adhered metal. Also disclosed is a sheet which can endure metal working processes and has high electromagnetic wave shielding properties, while resulting in a thin, very flexible fabric sheet. Specifically disclosed is an electromagnetic shielding sheet which is composed of a laminated nonwoven fabric that has at least a first layer and a second layer, and which is characterized in that the first layer is a layer of thermoplastic synthetic fibers having a fiber diameter of 6-50 μm, the second layer is a layer of extra-fine fibers having a fiber diameter of 0.1-5.0 μm, and a metal is adhered to at least one surface of the sheet.
