Problem to be solved: to appropriately control the temperature of the irradiation portion in the measuring apparatus.The measuring apparatus detects a first irradiation part (121) for irradiating the object to be measured (200), a heat transfer part (60) for transmitting heat generated by the first irradiation part to the heat sink (70), and a first temperature (T1) around the first irradiation part A target temperature setting section (430) for setting a second target temperature (t2v) based on a temperature detecting section (410), a first temperature and a first temperature target information (t1ref), and a second temperature detecting section (510) for detecting a second temperature around the heat transfer section SecondBased on the temperature and the second target temperature, there is provided a control unit (530) for controlling the heat transfer portion.Diagram【課題】計測装置における照射部の温度を好適に制御する。【解決手段】計測装置は、被測定対象(200)に光を照射する第1照射部(121)と、第1照射部により発生した熱を放熱部(70)に伝達する伝熱部(60)と、第1照射部の周囲の第1温度(T1)を検出する第1温度検出部(410)と、第1温度と第1温度目標情報(T1ref)とに基づいて、第2目標温度(T2v)を設定する目標温度設定部(430)と、伝熱部の周囲の第2温度を検出する第2温度検出部(510)と、第2温度と前記第2目標温度とに基づいて、伝熱部を制御する制御部(530)と、を備える。【選択図】図4
