<p>Concerning a resistance element comprising a laminated and sintered article of an insulating material substrate layer and a conductor layer formed on or embedded in the insulating material substrate layer, a material which is constituted of tungsten and carbon and has an atomic ratio of tungsten to carbon equal to 1:0.4 to 1:0.98 is used as said conductor layer. Such resistance element can be used at a temperature of 1400 DEG C or more and even further at a temperature of 1500 DEG C or more. The resistance element can increase its temperature rapidly to 1100 DEG C or more within about 3 seconds without any control circuit. The resistance element is a rapid temperature-rise resistance element with a high ignition performance constituted of ceramics with superior durability including resistance to repetitions of temperature increase and decrease, and resistance to oxidation at a high temperature. <IMAGE></p> |
