    摘要: A self-temperature controlling type heating device comprises a positive temperature coefficient ceramic resistor having a thin layer portion, a first electrode provided on one face of the thin layer portion, a second electrode provided on the other face of the thin layer portion opposite to the first electrode, and at least one third electrode provided on the surface of the PTC ceramic resistor in spaced relation to the first electrode. An electric current is allowed to flow between the first and second electrodes to form a heating element, and an electric resistance value between the first and third electrodes is detected to thereby make a temperature control. Thus, a high output is obtained at a low voltage and the control temperature is freely varied.
