Abstract
A sensor element, especially a temperature sensor (5) is proposed, having a sensitive area (11), whose electrical resistance changes under the influence of a temperature to which the sensitive area (11) is exposed. In this case, sensitive area (11) has a glass ceramic fusion (15) of a starting material containing at least one component which is furnished at least substantially with a surface metallization. The proposed temperature sensor (5) is especially suitable for use at temperatures in excess of 1000.degree. C., at which it shows resistance characteristics like that of a platinum resistor.
