Title:
MAGNETIC FIELD-SHIELDING ELECTROMAGNETIC SHIELDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/030635
Kind Code:
A1
Abstract:
[Problem] To provide, at low cost, a thin and lightweight electromagnetic shielding material which has good handling properties and good formability, and exhibits excellent electromagnetic shielding performance, especially excellent magnetic field shielding performance in a low frequency range.
[Solution] This magnetic field-shielding electromagnetic shielding material is obtained by providing the surface of a metal mixed woven fabric, which is obtained by mixed weaving a non-metal fiber such as a synthetic fiber and a metal wire (preferably at a constituent ratio of from 10:1 to 1:5), with a metal plating (preferably a copper plating or a copper-nickel plating). It is preferable that this magnetic field-shielding electromagnetic shielding material has a thickness of 1 mm or less.
