  • Patent number: 6175098
    Abstract: A plane heating element is provided which features reduced external electromagnetic waves. The plane heating element includes an upper input terminal and a lower input terminal in which upper wires and lower wires are spaced apart at a predetermined interval, and the currents through the respective wires flow oppositely to each other. First heat generation wires are connected to the upper input terminal at predetermined spaced intervals and have the same directed current flow as that of the upper input terminal. Second heat generation wires are connected to the upper input terminal at spaced intervals and have the oppositely directed current flow to that of the first heat generation wires.
