Claims

[Scope of utility model registration request]

It is arranged on the surface of an oxygen ion conductive solid electrolyte, has a sensor cathode in contact with the diffusion section, and a sensor anode in contact with the reference gas introduction section, and outputs a voltage according to the oxygen partial pressure ratio between these two electrodes. A sensor cell, a pump anode and a pump cathode are arranged on the surface of a rotating body electrolyte, and a pump cell pumps oxygen molecules in a diffusion section according to the value of a pump current supplied between these two electrodes, and a pump cell that pumps oxygen molecules in a diffusion section, and In the oxygen sensor, the oxygen sensor includes the diffusion section into which a gas to be measured is introduced through a diffusion-limiting section regulating the flow rate, and the reference gas introduction section into which a reference gas having a constant oxygen concentration is introduced, the pump anode of the pump cell being the reference point. An oxygen sensor characterized in that it is arranged in contact with a gas introduction part.
