Title:
ELECTROMAGNETIC WAVE SHIELDING SHEET, ELECTROMAGNETIC WAVE SHIELDING TRANSMISSION CABLE AND ELECTROMAGNETIC WAVE SHIELDING LSI
Document Type and Number:
WIPO Patent Application WO/2003/081973
Kind Code:
A1
Abstract:
An electromagnetic wave shielding sheet comprising, placed one upon another, a resistor layer (B) having an electric resistance not higher than 103 &ohm /&square or a conductor layer (A) and a magnetic body layer (C), where fine particles of a magnetic body are fixed by a dielectric binder. The electromagnetic wave shielding sheet is most suitable as a sheet for a transmission cable or an LSI and an electromagnetic wave shielding transmission cable or an electromagnetic wave shielding LSI coated with such a sheet suppresses its own electromagnetic wave radiation and is insusceptible to an external electromagnetic wave.
