Field of the Invention The present invention relates to an antenna device having a decorative portion on which particles of a conductive material are deposited. 2. Description of the Related Art An antenna device may be coated with a conductive material so that it looks metallic in design. For example, as shown in FIG. 3, a coil-shaped helical antenna element 2 is provided at the tip of an antenna device for a mobile phone, and the helical antenna element 2 is protected by an insulating cover 3. At the tip of the insulating cover 3 is attached a decorative portion 4 to which nickel chrome plating, which is a conductive material, is applied to give a metallic appearance. However, when a conductive material is provided near the antenna element, the magnetic field of the conductive material hinders transmission and reception of the antenna. For example, the required performance cannot be obtained unless the helical antenna element 2 and the decorative portion 4 plated with nickel and chrome are separated by 2 mm or more. For this reason, the size of the antenna device increases, which hinders miniaturization of the mobile phone device. SUMMARY OF THE INVENTION [0004] An antenna device of the present invention has been made in view of the above point. In an antenna device having an antenna element and a decorative portion disposed near the antenna element, The decorative portion is deposited on the insulating material such that particles of the conductive material do not contact each other. Embodiments of the present invention will be described with reference to the drawings. The antenna device of this embodiment is an antenna device used for a mobile phone. FIG. 1 is a plan view showing a configuration of a main part of the antenna device, and a cross section of a tip portion. The antenna device has a rod-shaped rod antenna element 1 and a helical helical antenna element 2 provided at the tip of the rod antenna element 1. The helical antenna element 2 is protected by an insulating cover 3, and a decorative portion 4 having a silver appearance is attached to the tip of the insulating cover 3 to give a metallic appearance. As shown in FIG. 2, the decorative part 4 is made of an insulating material 41.
Is deposited so that the particles 42 of the conductive material do not come into contact with each other.
Reference). This discontinuous deposition is formed by stopping the growth of nuclei in the process of growing a thin film by vacuum deposition in a state where the nuclei do not contact each other. Due to this discontinuity, the magnetic field does not increase, and electrical conduction does not occur. Therefore, transmission and reception of the helical antenna element 2 are not hindered. In addition, there is no limitation on the distance between the helical antenna element 2 and the decorative portion 4, and the size can be reduced. [0007] Since the particles of the conductive material discontinuously deposited are not in contact with each other, the magnetic field is minimal. This does not hinder transmission and reception of the antenna.
