PURPOSE:To enable the reduction in the thickness of a wristwatch and to attain to reduce the cost of a circuit block by hoop production, by supporting a thin flexible circuit board by an elastic metal plate. CONSTITUTION:The structure of a circuit part is formed of a flexible circuit board 25, an elastic metal plate 21 having a size and shape capable of covering the greater part of said circuit board 25 and a substrate 1. The board 25 forms a configuration interposed between the substrate 1 and the metal plate 21. A contact part by a conductive pattern is provided to the substrate 25 and contacted with the part to be contacted provided to other watch parts under pressure by pressing force due to the elasticity of the metal plate 21 to take continuity. Further, the metal plate 21 holds at least a part of electronic parts by pressing force due to the elasticity thereof. By this mechanism, a connection structure becomes simple and a space also becomes small and large effect is imparted to the thickness reduction, miniaturization and cost reduction of the watch. |
