Abstract
An electromagnetic wave absorbing shielding material which is thin and lightweight and shows high electromagnetic wave absorbing capacity in a wide frequency region. The material comprises: (1) a one-dimensional conductive segment pattern which is a conductive segment pattern formed from a conductive material, wherein the conductive segment pattern has a length of more than 1/2 of the wavelength of the subjective electromagnetic wave, and the segment pattern has no electrical connection therebetween, (2) an electromagnetic wave shielding layer, and (3) an insulating intermediate material having a thickness of 0.1-10.0 mm, located between the one-dimensional conductive segment pattern (1) and the electromagnetic wave shielding layer (2).
