ABSTRACT:
First and second solid electrolyte bodies are opposed to one another to form a reference gas chamber therebetween. A measurement cell for detecting an air fuel ratio in measurement gas is provided on the first solid electrolyte body with a measurement electrode exposed to the measurement gas and a reference electrode exposed to the reference gas chamber. An oxygen pump cell is provided on the second solid electrolyte body with a first pump electrode exposed to the measurement gas and a second pump electrode exposed to the reference gas chamber. When a voltage is applied to the first and second oxygen pump cell, the oxygen gas is introduced from the measurement gas into the reference gas chamber.
