Abstract
An electrochemical sensor for ascertaining gas concentrations in gases, particularly in exhaust gases of combustion engines, includes an oxygen-ion-conductive solid electrolyte which is provided with electrode layers arranged at a distance from one another and with at least one resistance heating element that is separated from the solid electrolyte by an electrical insulating layer, a foil binder layer being provided between the electrical insulating layer and the solid electrolyte. At least one electron-conductive intermediate layer is provided between the electrode-side electrical insulating layer and the adjacent solid electrolyte.
