部分に欠除部３ａを有して開ループとなっている。Example Hereinafter, an electric device of an example of the present invention will be described with reference to the drawings. FIG. 1, FIG. 2 and FIG. 3 show an embodiment of the present invention. The cabinet main body 2 composed of the first resin molded body that cannot be plated is integrally molded with the second resin molded body that can be plated as a decorative body, and the surface of the second resin molded body is plated with metal. By applying
The ring-shaped metallic ornament 3 is configured. The portion of the metal decorative body 3 formed by this plating is shown by hatching. The decorative body 3 is provided corresponding to the ferrite antenna 1 housed inside the cabinet body 2, and has an opening 3a in a part to form an open loop.
