Abstract
A high sensitive and high responsive gas detecting sensor for detecting the partial pressure of oxygen gas in the exhaust gases is disclosed. The sensor is provided with a sensing element having an electrical characteristic in response to the partial pressure of oxygen gas, a ceramic base member which supports the sensing element so that the sensing element is exposed to the exhaust gases, and electric current conducting means for supplying an electric current to the sensing element. The sensing element is formed of alloy ceramic material composed of 20 to 60 mol percent of cobalt monoxide, 20 to 60 mol percent of magnesium monoxide and 10 to 50 mol percent of nickel monoxide. In the preferred embodiment, the base member is formed into a plate shape and the sensing element is formed on the base member like a film.
