り易かった。(Problems to be Solved by the Invention) By the way, in the ceramic heaters 1 and 2 shown in FIGS. 3 and 4, the ceramic heating element 3.
4 and the lead wire 6.6' undergo thermal expansion and thermal contraction, but since there is a large difference in thermal expansion coefficient between the ceramic heating element 3.4 and the lead wire 6.6', the mechanical lead wire 6. If the 6' screw is tightened and fixed, it tends to loosen with use over time, resulting in poor energization or damage. IA6.6' easily came off and became unusable.
そこで本発明は、セラミックス発熱体とリード線とが熱

Moreover, the brazing material has heat-resistant strength, so when the ceramic heater generates electricity,
It can sufficiently cope with the difference in thermal expansion between the ceramic heating element and the lead wire, and no cracks will occur at the joint surface of the ceramic heating element. Therefore, even if the lead wire is used for many years, the lead wire will not peel off from the ceramic heating element.
