Sensorelement (10) zur Erfassung mindestens einer Eigenschaft eines Messgases in einem Messgasraum, insbesondere zur Erfassung eines Anteils einer Gaskomponente in dem Messgas oder einer Temperatur des Messgases, umfassend ein erstes Substrat (22), ein zweites Substrat (30) und einen Sensorchip (14), wobei der Sensorchip (14) mindestens eine Festelektrolytmembran (24), eine erste Elektrode (26) und eine zweite Elektrode (28) aufweist, wobei das erste Substrat (22) und das zweite Substrat (30) miteinander mittels mindestens einer Glaskeramik (32) verbunden sind, wobei die Glaskeramik (32) aus einem Material hergestellt ist, das mindestens SiO2, MgO, Al2O3, und weiterhin ZnO und/oder B2O3aufweist. A sensor element for detecting at least one property of a measuring gas in a measuring gas chamber, in particular for detecting a portion of a gas component in the measuring gas or a temperature of the measuring gas. The sensor element includes a first substrate, a second substrate, and a sensor chip. The sensor chip includes at least one solid electrolyte diaphragm, a first electrode, and a second electrode. The first substrate and the second substrate are connected to each other via at least one glass ceramic. The glass ceramic is manufactured from a material which includes at least SiO2, MgO, Al2O3, as well as ZnO and/or B2O3.
