A temperature sensor includes a sensor tube and a sensor rod received in the sensor tube and having a thermal expansion coefficient which differs from a thermal expansion coefficient of the sensor tube. The sensor rod has one end, which is supported by a free end of the sensor tube, and another end, which forms an actuating element of a switching contact assembly. An insulating member at least partly surrounds the switching contact assembly and has an opening for passage of the sensor tube with accommodated sensor rod. Mounted to the insulating member in the area of the opening is a support plate which is connected at least indirectly to the sensor tube by a welding process such that an opening-surrounding wall portion of the insulating member is held in place.
