To hold transparency capable of transmitting visible radiation, to transmit only an electromagnetic wave of a specified frequency, and to easily execute electromagnetic shield for window glass or the like.
This electromagnetic wave shielding material 1 is constituted by arranging through holes 20 having a prescribed shape and a prescribed dimension on a face of a transparent conductor layer 10 transmitting visible light, and is made to transmit only electromagnetic waves of prescribed frequency corresponding to the shape and the dimension of the through holes 20. An electromagnetic wave shielding material 1A is also arranged with a plurality of kinds of through holes 20A and 20B wherein at least one of the shape and the dimension is different, and is made to transmit the electromagnetic waves of plurality of frequencies corresponding to the plurality of kinds of through holes 20A and 20B.
