Abstract

A sensor element having a layered construction and configured to detect a physical property of a gas or a liquid includes a functional component situated in the interior, which functional component is connected electrically to a conductor element, which conductor element extends up to the outer surface or up into the surroundings of the sensor element. The sensor element has at least one sealing element which adjoins the functional component and/or the conductor element. The conductor element and the at least one sealing element are configured to be gas-tight at least regionally in the interior of the sensor element and are situated in such a way that the functional component is separated gas-tight from the surroundings of the sensor element.
