The hexahedron is preferably contained in an amount of 0.2 to 40 parts by weight, more preferably 0.2 to 20 parts by weight, based on 100 parts by weight of the resin. When the hexacrystalline stone is less than 0.2 part by weight, the effect of preventing electromagnetic waves is insignificant, and when it exceeds 40 parts by weight, an excessive amount of the electromagnetic wave preventing synergistic effect does not appear, resulting in waste of raw materials.

The above-mentioned materials contained in the functional resin composition of the present invention are preferably 0.1 to 100 µm, except for nanometals, and are obtained by crushing to have micron units through a crushing apparatus and then passing through the screen. The smaller the composition particles are, the more favorable the dispersion is achieved in the particle range of the above range to exhibit the intrinsic properties of each material.
