Abstract

The electromagnetic wave shielding material of the present invention is formed by a plurality of layers, wherein the plurality of layers, from the side closest to the electromagnetic wave source, sequentially comprises: an incident layer: with a thickness of 1 to 200 μm, formed of a material having a real part of dielectric constant of 5 to 100 and a dielectric loss tangent of 0.2 to 2; a spacer layer: with a thickness of 10 to 500 μm, formed of a material having a real part of dielectric constant of 1 to 10 and a dielectric loss tangent of 0 to 0.2; and a shielding layer: with a thickness of 1 to 100 μm, formed of a material having a real part of dielectric constant of 50 or more and a dielectric loss tangent of 1 or more. none
