Abstract

A fast-responding temperature sensor, for measuring temperature of a medium, features a resistance element (12) formed as a film on an insulating substrate (10). The resistance element is disposed in a bubble or dome (11) of ceramic, preferably glass ceramic, which is formed on, and bowed with respect to, the insulating substrate (10).
