Fine thermoelectric elements were fabricated on electrode chips by welding together the tips of thin 5 μm diameter Pt and W wires by Joule heat welding. The Pt/W junction was heated by bringing it into contact with a wire carrying a current, thus generating a voltage due to the Seebeck effect in the circuit containing the junction. The Pt/W junctions of two thermoelectric elements in separate circuits were brought into contact with each other. Current was supplied to one of the thermoelectric elements, while the temperature was measured using the other element as a thermocouple. The temperature, which is due to the Peltier effect, was found to depend on the direction of current supply.
