The number of turns of the coil wound along the circumference of the ornamental water tank is not particularly limited, but is preferably 20 to 200 turns, more preferably 40 to 60 turns, and 50 More preferably, it is a turn. Further, when the number of coil windings is more than 200 turns, the coil generates heat, so that the temperature inside the ornamental display is likely to rise, and the liquid stored in the ornamental display tends to evaporate. When the number of windings of the coil is less than 20 turns, the strength of the electromagnetic field generated by the coil is weakened, and the induced current of the power generating coil is weakened. The ornamental water tank provided with two or more coils wound in the number of times in the above range is easy to give a constant induction power to the power generation coil included in the model in the liquid stored inside the ornamental water tank. Therefore, it can be suitably used for an ornamental display device. Although the voltage at the time of energizing the coil for electromagnetic field generation with which the ornamental water tank is provided is not particularly limited, it can be used in the range of 100V to 200V.
