摘要： In accordance with the present invention, there is provided an exhaust gas sensor which comprises an oxygen pump cell made of solid electrolyte having an oxygen ion conductivity, an oxygen sensor cell made of solid electrolyte having an oxygen ion conductivity and disposed in opposition to the pump cell in such a manner as to define therebetween a detection space, and a semiconductor detection element made of oxide semiconductor and disposed in the detection space for detecting a predetermined detected substance in the exhaust gas introduced to the detection space. The concentration of oxygen in the detection space is regulated so as to be included within a predetermined range through control of charge or discharge of oxygen into or from the detection space by means of the oxygen pump cell on the basis of the concentration of oxygen in the exhaust gas, which is detected by the oxygen sensor cell.
