Sensor element containing a sealing element for a functional component

A sensor element for detecting one of a concentration of a gas component or a temperature of an exhaust gas of an internal combustion engine, comprising:

• a functional component situated in interior portion of the sensor element;
• a conductor element, wherein the functional component is connected electrically conductive to the conductor element, and wherein the conductor element extends one of (i) up to an outer surface of the sensor element or (ii) up into surroundings of the sensor element;
• and
• at least one sealing element adjoining at least one of the functional component and the conductor element, wherein:
• the conductor element and the at least one sealing element are (i) configured to be gas-tight at least regionally in the interior of the sensor element and (ii) situated in such a way that the functional component is separated in a gas-tight manner from the surroundings of the sensor element, and wherein the sensor element has a layered construction,
• the functional component is situated between a first ceramic layer and a second ceramic layer;
• the conductor element and the at least one sealing element are at least partially situated and gas-tight between the first and the second ceramic layers,
• the conductor element and the at least one sealing element are positioned in such a way that the functional component is separated gas-tight from the surroundings of the sensor element,
• the sensor element has a feed-through extending from the outer surface of the sensor element through at least one ceramic layer up to the plane of the functional component, and
• at least one of the sealing element and the conductor element is at least partially situated inside the feed-through and gas-tight in a region inside the feed-through, wherein the sealing element has a cavity, and wherein at least a part of the conductor element is situated in the interior of the cavity.
