In a temperature probe, in particular for use in the waste-gas diffusor of a gas turbine, a probe tube (1) projecting into the hot-gas region of the waste-gas diffusor is provided with an inner bore running in the direction of the tube axis of the probe tube (1). At the same time, the probe tube (1) is provided over its length with a number of throughflow ducts running transversely relative to the tube axis and in which are located a number of thermocouples (22), the connecting points (23) of which are arranged in the throughflow ducts. The thermocouples (22) are connected to a compensating line (13) in a terminal box (14). Each thermocouple (22) is arranged in a solely heat-movably guided manner in a protective tube (18) which is fixed relative to the inner bore of the probe tube (1).
