Electromagnetic Wave Shielding Material, Covering Material or Exterior Material, and Electric/Electronic Apparatus

Abstract

Provided is an electromagnetic wave shielding materials having an improved shape retention property. The electromagnetic wave shielding material includes a laminate with at least one non-magnetic resin layer and at least one non-magnetic metal layer and/or at least one ferromagnetic layer, wherein a value of an anisotropy at break (Rc) represented by the following equation (1) is 0 or less or 1 or more: [ Equation ⁢ 1 ] Rc = ln ⁢ ( W W 0 ) ln ⁢ ( t t 0 ) ( 1 ) in which: Rc is an anisotropy at break; W is a width (mm) of a ruptured portion after a tensile test of the laminate; W0 is a width (mm) of the laminate before the tensile test; t is a thickness (μm) of the ruptured portion after the tensile test of the laminate; and t0 is a thickness (μm) of the laminate before the tensile test.

Dependencies are inferred from the claim text.
