PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding resin composition exhibiting an excellent electromagnetic wave shielding performance but not causing a quality degradation in signals transmitting through wiring patterns in high-frequency regions beyond 1 GHz without the use of any external component. SOLUTION: The electromagnetic wave shielding resin composition is prepared by a method wherein 46 parts of a liquid epoxy resin, 4.5 parts of a latent hardener, 49.5 parts of additives, 1,528 parts of coated particles prepared by providing a ferrite plate on carbonyl iron particles having an average particle diameter of 3μm, and 83 parts of a solvent, are mixed in a mixer and then kneaded in a three-roll mill.
