<P>PROBLEM TO BE SOLVED: To provide a wrist watch having radio functions with a sense of quality in appearance. <P>SOLUTION: An antenna 17 for receiving long-wave standard radio waves is stored in a case constituted of a casing 12, a casing 13 and a back lid 14. The casing 12 is constituted of a conductor material, such as stainless steel, brass or titanium, and notched parts C1, C2 are formed on parts corresponding to coil both ends of the stored antenna 17. The long-wave standard radio wave is received by the antenna 17 through the notched parts C1, C2. The casing 12 is constituted of a non-conductor. The back lid 14 is formed, by fitting a discoid part 142 constituted of a non-conductor material, such as, a glass material to an outer frame 141 constituted of a conductor material, such as, a stainless steel, brass or titanium. The discoid part 142 is finished so as to have an appearance similar to that of a metal material by surface treatment. According to the case having this constitution, the wrist watch with radio functions can receive long-wave standard radio wave, and has a sense of luxury in the appearance. <P>COPYRIGHT: (C)2009,JPO&INPIT |
