To provide a decorative device allowing providing of a plurality of decorative bodies and performing decoration and time display by the linked natural operation.

Each of a plurality of decorative bodies 6 is driven by wire made of shape memory alloys. The wire is contracted when the wire is heated by a driving means and imparts tensile force to the decorative bodies. By driving the decorative bodies 6 by the wire in this way, a driving mechanism can be miniaturized/thinned. Therefore, the whole of the device is not increased in scale, even if the plurality of decorative bodies 6 are provided. Because the decorative bodies 6 are operated by contraction of the wire, noise is not generated and also the operations become smooth and natural.
