Abstract: Proposed is a temperature relation equation derivation method which includes irradiating a same point of a target substance with heating light for heating the target substance and measurement light for detecting a change of a reflectivity of the target substance caused by the heating light, detecting light of detecting intensity of each of incident light and reflected light of the measurement light, and calculating of deriving a temperature relation equation based on the reflectivity of the target substance by using a value detected in the detecting of light.
