ABSTRACT:
Provided is a multilayer gas sensing element having a high measurement accuracy and less susceptible to a leakage current. The element comprises an oxygen pump cell for adjusting an oxygen concentration in a measured gas chamber, a sensor cell for detecting a specified gas concentration in the measured gas chamber, and a heater for heating the cells up to an activating temperature. The heater includes a heat generator for generating heat when energized, a heater terminal provided externally and a heater lead for making electrical connection therebetween. When the electrical resistance value of the heat generator is taken as RH and the electrical resistance value of the heater lead is taken as RL, these values are set to satisfy the relationship of 1.5≦RH/RL.
