Abstract
The cermaic heater includes an elongated plate-like ceramic substrate, a resistance heating element arranged on the ceramic substrate and a pair of conductive lead members extending from the resistance heating element and having a specific resistance smaller than that of the resistance heating element. The oxygen sensor element includes a heater unit and a sensor unit, wherein the heater unit has an elongated plate-like ceramic substrate and a resistance heating element and a pair of conductive lead members arranged thereon, and the sensor unit is integrally united with the heater unit and includes an oxygen ion-conducting solid electrolyte body and reference and measuring electrodes and conductive lead members formed thereon.
