Abstract

There is provided an annealing device including a heating unit that heats a surface of an annealing object to temporarily melt an outer layer portion, a sensor that detects thermal radiation light from the annealing object heated by the heating unit, and a processing unit that estimates an annealing result of the annealing object on the basis of a waveform showing a temporal change in an intensity of the thermal radiation light detected by the sensor.
