A temperature sensor for temperature measurement in the gap between ceramic hot plates and radiant heating elements has at least one sensor element (3), which is at least partially enclosed by a trough-shaped protective housing (1) made of heat-resistant ceramic. The sensor element (3) provided with electrical connection lines is arranged in the region of one end or at the tip of the protective housing (1), while the electrical connection lines (4) are guided out through the other end of the protective housing. A temperature-dependent electrical measuring resistor with a resistive layer is used as the sensor element (3), wherein the resistive layer has at least one metal from the platinum metal group. The measuring resistor is fixed in the end region (20) of the protective housing (1) using a ceramic grout or is secured against falling out by capping it with a mica cover (7). At the other end of the protective housing the electrical connection lines (4) are constructed as plug contacts.
