Disclosed is an electromagnetic wave-shielding coating material which is superior in both paintability and a electromagnetic wave shielding activity. Also, the coating material is of antistatic activity. The coating material comprises polyaniline (ES) with a solid content of 1-50%, a matrix polymer with a solid content of 1-50%, and additives at a predetermined amount. Also disclosed is an electromagnetic wave-shielding coating material, which is prepared by mixing polyaniline (ES, 100%), an acrylic resin and additives at predetermined amounts and adding the mixture with a hardener and a mixed solvent at predetermined amounts just before use. The electromagnetic-shielding coating material is able to effectively shield electromagnetic waves with a broad band of frequencies and be coated onto cases of various electromagnetic apparatuses, thereby protecting the body from electromagnetic wave pollutions.
