    摘要: The present invention provides a method of manufacturing an electromagnetic wave shielding plastic molding, which comprises the step of, without prior washing and without providing a primer layer, or after providing a water-soluble primer layer, forming a conductive layer comprising at least one selected from the group consisting of Al, Cu, Ni, Cr and Sn and alloys thereof by high-frequency excited plasma. The electromagnetic wave shielding plastic molding thus-produced has excellent in electromagnetic wave shielding effects, adhering strength, humidity resistance and hardness, has economic advantages, and hence is useful as an electromagnetic wave shield for a plastic molding, such as the housing for a portable telephone.
