PURPOSE:To quickly remove moisture from an automobile window pane, by providing the pane with a heater made of a transparent electroconductive film and by supplying electricity to the heater to heat. CONSTITUTION:A heater 2 is made of a transparent electroconductive film of 8,000Angstrom in thickness on a side pane 1. Electrodes 3 are provided on the ends of the heater 2. The transparent electroconductive film is of ITO. The electrodes 3 are of aluminum. The electrodes are connected to a battery 5 through lead wires 4. The heater 2 is shaped as an inverted U to make its electric resistance highest in the central part as shown by a dotted line in the drawing, so that the calorific value is the largest in the central part when electricity is applied. As a result, moisture is removed starting with the central part. |
