PURPOSE:To obtain a small-sized electronic wrist watch having sufficient power generation capacity by connecting specified number or more of n-type and P-type semiconductors, each comprising a thin film of specific thickness or less, alternately in series and fixing the semiconductors by means of an insulator to constitute a thermoelectric element thereby storing the generated current and driving an electronic watch. CONSTITUTION:2000 pieces or more of n-type semiconductors 103 and P-type semiconductors 104 of 0.1-3mm thick are connected alternately in series and secured by means of insulators 101 (heat absorbing side) and 102 (heat discharging side) made of silicon thus constituting a thermoelectric element 107. Thermoelectromotive force is then generated based on the temperature difference between the arm side body (heat absorbing side) and the movement side (heat discharging side). An electron flow thus generated is taken out from the output terminal parts 106, 106 through a connecting part 105 and fed to a storing means 108. When the voltage of the storing means 108 reaches a predetermined level, a time indication means 109 is driven. |
