Summary:PROBLEM TO BE SOLVED: To provide a method for measuring a workpiece temperature that can accurately measure change in temperatures of a heated workpiece during cooling of the workpiece, without fixing a thermocouple to the workpiece.SOLUTION: There is provided a method for measuring the temperature of a workpiece heated in a workpiece heating step and then cooled in a cooling room (including a naturally cooling room), which can obtain a measurement value close to an actual temperature by measuring the temperature of the workpiece heated and then put into the cooling room, with a two-color radiation thermometer.SELECTED DRAWING: None 【課題】ワークに熱電対を付設することなく、加熱されたワークの冷却中の温度変化を正確に測定できるワーク温度の測定方法を提供する。【解決手段】ワークの熱処理工程で加熱後に冷却室（放冷室を含む）にて冷却されるワークの温度測定方法であって、加熱された後に前記冷却室内に装入されたワークの温度を二色放射温度計で測定することにより、実温度に近い測定値を得る。【選択図】なし
