ELECTROMAGNETIC SHIELDING MATERIAL

Document Type and Number:

WIPO Patent Application WO/2016/157554

Kind Code:

A1

Abstract:

Provided is an electromagnetic shielding material having excellent electromagnetic shielding properties, lightweight properties, and molding workability. The electromagnetic shielding material has a structure in which at least three sheets of metallic foil are laminated with insulation layers respectively therebetween, wherein a combination of all of the metallic foils and insulation layers forming the electromagnetic shielding material satisfies σM×dM×dR≥3×10-3, where the symbols in the formula are as follows: σM represents the conductive rate (S/m) in the metallic foils at 20°C; dM represents the thickness (m) of the metallic foils; and dR represents the thickness (m) of the insulation layers.
