Abstract
An oxygen sensor comprising an oxygen ion conductive solid electrolyte which contains fluorine at least in the surface region on the side having contact with a gas to be tested. This oxygen sensor is characterized in that the change of the electromotive force at an O.sub.2 /CO molar ratio of about 0.5:1 is very large even if the temperature is as low as 350.degree. C.
