PURPOSE: A manufacturing method of a synthetic resin shielding an electromagnetic wave is provided to shield an electromagnetic wave in manufacturing covers of various electronic devices such as a cellular phone, a telephone, and so on. CONSTITUTION: A plurality of synthetic resin films(1)(3) which form a surface of a synthetic resin product are integrally deposited on a metal screen(5). The metal screen(5) is formed in a metal net and coated at its both surfaces. The deposited film is subjected to a pressure forming to a certain shape. The pressure formed film is cut correspondingly to an outline of a cover of an electronic device like a cellular phone. The cut film is installed in a mold. A synthetic resin which is molten on the metal screen(5) of the film is injected. The synthetic resin films(1)(3) are transparent. The rear surfaces of the synthetic resin films(1)(3) are printed in a decoration pattern.
