Abstract
A thermocouple device for detecting a flame. The device includes an outer thermocouple element having an excellent corrosion resistance and a large thermoelectromotive force, an inner thermocouple element, which is inserted into the outer thermocouple element, having a large thermoelectromotive force, and a junction layer securing end portions of the inner and outer thermocouple element. The junction layer is formed with a soldering material so as to avoid the formation of an alloy of the element materials that would have a poor corrosion resistance normally formed by welding.
