A sensing element has a cup-shaped solid electrolytic body with one end closed and an inside space serving as a reference gas chamber, a sensing electrode provided on an outer surface of the solid electrolytic body so as to be exposed to measured gas, and a reference electrode provided on an inner surface of the solid electrolytic body so as to be exposed to reference gas in the reference gas chamber. A heater is disposed in the reference gas chamber. The solid electrolytic body has a leg consisting of a proximal portion and a distal portion. The distal portion is thinner than the proximal portion. And, the heater is brought into contact with a surface defining the reference gas chamber at least partly in the region of the distal portion.
