The invention discloses an aircraft surface temperature sensor and an aircraft surface temperature sensor probe. The probe adopts at least two thermocouple wires, an aluminum oxide ceramic tube sheathed to at least two thermocouple wires, and a probe outer wall sheathed to the aluminum oxide ceramic tube, wherein two thermocouple wires are at least selected to be welded on one end which is near anouter tested surface, a welded welding spot and the end surface, which is near the outer tested surface, of the probe outer wall are both level with the outer tested surface. The outer surface of thetemperature sensor has small holes, high-density measurement point arrangement is guaranteed, an installation hollow position is small, and the surface morphology of the aircraft is kept complete. Through structure design, the surface of the sensor probe is guaranteed to be level, response speed is high, and the probe can adapt to a convection environment, can obtain original transition characteristics, is high in measurement accuracy and belongs to the field of aircraft measurement.
