The invention relates to a sensor element, particularly provided to detect a physical property of a gas, particularly to detect the concentration of a gas component or the temperature or of a solid constituent or of a liquid constituent of an exhaust gas from an internal combustion engine, wherein the sensor element (20) comprises a first end region (201) and a second end region (202) arranged opposite one another in the longitudinal direction of the sensor element, wherein said sensor element (20) comprises a functional element (31, 311, 312) in the first end region (201) in the interior of the sensor element (20), which function element is electrically conductively connected with a contact surface (43, 44, 45) arranged in the second end region (202) on the outer surface of the sensor element (20), wherein the electrically conductive connection between the function element (31, 311, 312) and the contact surface (43, 44, 45) comprises a conductor track (321, 322, 328) in the interior of the sensor element (20) essentially running in the longitudinal direction thereof and a lead-through (501, 502, 503) running essentially perpendicular to the longitudinal direction of said sensor element characterised in that an electrical resistance of the conductor track (3211, 322, 328) and an electrical resistance of the lead-through (501, 502, 503) are in a relationship to one another that is not greater than 3 and not less than 1/3.
