Title:
ガスセンサ
Document Type and Number:
Japanese Patent JP5425833
Kind Code:
B2
Abstract:
A reference electrode 42 and a measurement electrode 44 are formed directly on the same first solid electrolyte layer 4. Thus, heat from a heater 72 is transferred from a third substrate layer 3 and the first solid electrolyte layer 4 in this order. The heat is transferred from the heater 72 to the reference electrode 42 and the measurement electrode 44 through the same first solid electrolyte layer 4. Since the reference electrode 42 is covered with a reference gas introduction layer 48 formed of a porous body, compared to transference of heat from the heater 72 to the reference electrode 42 through the first solid electrolyte layer 4 on which the reference electrode 42 is formed directly, transference of heat from the heater 72 to the reference electrode 42 through the reference gas introduction layer 48 is smaller. This suppresses occurrence of a situation that causes the temperature difference between the reference electrode 42 and the measurement electrode 44 due to heat from the heater 72. Thus, variation in an electromotive force V2 generated between the reference electrode 42 and the measurement electrode 44 can be decreased.
