Abstract
An annealing object is held at a position on which a laser beam output from a laser light source is incident. An infrared detector detects heat radiation light from the annealing object. An optical element which does not allow light having a wavelength shorter than 1 μm to be incident on the infrared detector is disposed in a pathway of the heat radiation light from the annealing object to the infrared detector.
