An oxygen sensor made up of an oxygen concentration cell which as a stratiform structure and includes a thin film of an oxygen ion conductive solid electrolyte and a thin layer of a material serving as the source of a reference oxygen partial pressure such as a Ni-NiO system, an electrically nonconductive base plate which supports thereon the cell, and a thin metal layer embedded in the base plate as a resistance heating element for heating the solid electrolyte film.
