The present invention relates to an electromagnetic wave shielding material, and the main purpose of the present invention is to provide an electromagnetic wave shielding material, which can effectively shield an electromagnetic wave while being transparent by using a nanostructure, and enables a reduction in manufacturing costs and cost reduction by means of a simplified manufacturing process. To this end, disclosed is an electromagnetic wave shielding material using a nanostructure, the electromagnetic wave shielding material comprising: a support substrate; and a nano double lattice structure formed by allowing nano metal wires having a line width and height of nanometer (nm) scale to be bonded and fixed to a surface of the support substrate in a state in which closed curves are formed, and having a structure in which the closed curves formed by the nano metal wires are repeatedly arranged on the surface of the support substrate, wherein a nano double lattice characteristic constant corresponding to a diameter of a circle having a minimum area among circles surrounding one of the closed curves in the whole nano double lattice structure is formed so as to be the same as or smaller than a wavelength of an electromagnetic wave to be shielded, and in the arrangement of the closed curves, a pitch between the closed curves is the same as or smaller than the wavelength of the electromagnetic wave to be shielded, and the line width of the nano metal wires of the nano double lattice structure is the same as or smaller than 1/2 of the pitch. |
