PROBLEM TO BE SOLVED: To obtain a high frequency electromagnetic shield having a simple structure and a high effect. SOLUTION: A means for upgrading an electric contact of a part having a high current density of a current component flowing to a ground pattern of a board from a shield case of a high frequency induced current induced in the case when a radio wave is radiated from an antenna, as compared with that of the other part is provided. Or, the case is constituted of a member having a conductive film formed on the surface of a resin, and an anisotropic magnetic film is further laminated on the conductive film, and the current flowing to the antenna the magnetization difficulty axial direction of the magnetic film is set the same direction as the current flowing to the antenna.
