Abstract
A sensor element is used to detect a physical property of a measuring gas, preferably to determine the oxygen content or the temperature of an exhaust gas of an internal combustion engine. The sensor element contains a first solid electrolyte layer and a second solid electrolyte layer. A first printed conductor and a second printed conductor are provided on opposite sides of the first solid electrolyte layer, the first printed conductor including a first electrode and a feed line to the first electrode, and the second printed conductor including a second electrode and a feed line to the second electrode. A third printed conductor, which includes a third electrode and a feed line to the third electrode, is provided on the second solid electrolyte layer. The second printed conductor is positioned between the third electrode and the first printed conductor.
