The present invention is formed of an insulating film on the surface, magnetic particles for absorbing electromagnetic waves; And a conductive metal body for shielding electromagnetic waves, but between the conductive metal body and the magnetic particles to prevent the magnetic permeability from falling due to the eddy current generated when the magnetic particles are in direct contact with the conductive metal body. It provides an electromagnetic wave protective composition, characterized in that the insulating film is configured to be interposed. |
