Sensor element, in particular for detecting a physical property of a gas, in particular for detecting the concentration of a gas component or the temperature or a solid component or a liquid component of an exhaust gas from an internal combustion engine, wherein the sensor element has a first end region and a second end region opposite one another in its longitudinal direction, wherein the sensor element has in the first end region, in the interior of the sensor element, an electrical resistance heater, which is connected in an electrically conducting manner to a first contact area, arranged in the second end region on the outer surface of the sensor element, wherein the electrically conducting connection between the resistance heater and the first contact area has a first printed conductor, running substantially in the longitudinal direction in the interior of the sensor element, wherein the electrically conducting connection between the resistance heater and the first contact area has in addition to the first printed conductor, interacting with it, a first lead-through, which runs substantially perpendicularly to the longitudinal direction of the sensor element, wherein the first lead-through consists of a conductive coating of the radial wall of a first plated-through hole of the sensor element, wherein the sensor element also has a reference gas duct, running substantially in the longitudinal direction of the sensor element and communicating by way of a reference gas opening with a reference gas located outside the sensor element, wherein the reference gas duct is arranged without overlapping the first lead-through in plan view of the sensor element, wherein the first printed conductor and the reference gas duct are arranged such that there is between them a first at least partial overlap in plan view of the sensor element, wherein, at its end away from the end region of the sensor element, the first printed conductor is angled away by an angle (α) of no more than 25°, in particular no more than 14°, and no less than 2°, in particular no less than 5°, in relation to the outer side of the sensor element, and wherein the resistance heater is connected in an electrically conducting manner to a second contact area, arranged in the second end region on the outer surface of the sensor element, wherein the electrically conducting connections between the resistance heater and the second contact areas has a second printed conductor, running substantially in the longitudinal direction in the interior of the sensor element, and wherein the second printed conductor and the reference gas duct are arranged such that there is between the second printed conductor and the reference gas duct a second at least partial overlap in plan view of the sensor element and wherein, at its end away from the first end region of the sensor element, the second printed conductor is angled away by an angle (α) of no more than 25°, in particular no more than 14°, and no less than 2°, in particular no less than 5°, in relation to the outer side of the sensor element, wherein the electrically conducting connection between the resistance heater and the second contact area has a second lead-through, which runs substantially perpendicularly to the longitudinal direction of the sensor element, wherein the second lead-through consists of a conductive coating of the radial wall of a second plated-through hole of the sensor element, wherein the reference gas duct is arranged without overlapping the second lead-through in plan view of the sensor element, wherein the sensor element has in the first end region, in the interior of the sensor element, a two-dimensionally formed cermet electrode, which communicates with the exterior space of the sensor element by way of the reference gas duct and is connected in an electrically conducting manner to a third contact area, arranged in the second end region on the outer surface of the sensor element, wherein the electrically conducting connection between the cermet electrode and the third contact area has a third printed conductor, running substantially in the longitudinal direction in the interior of the sensor element, wherein the electrically conducting connection between the cermet electrode and the third contact area has in addition to the third printed conductor, interacting with it, a third lead-through, which runs substantially perpendicularly to the longitudinal direction of the sensor element, wherein the third lead-through consists of a conductive coating of the radial wall of a third plated-through hole of the sensor element and the reference gas duct is arranged without overlapping the third lead-through in plan view of the sensor element, wherein the third printed conductor and the reference gas duct are arranged such that there is between them a third at least partial overlap in plan view of the sensor element, wherein, at its end away from the first end region of the sensor element, the third printed conductor is angled away by an angle (α) of no more than 25°, in particular no more than 14°, and no less than 2°, in particular no less than 5°, in relation to the outer side of the sensor element.
