Problem to be solved: to provide a deep body temperature estimation device which can easily estimate the deep temperature.The first measuring section 101 measures the heart rate of the subject to be measured.The second measuring section 102 measures the temperature of the atmosphere of the measurement subject.The first operation unit 103 obtains the heat quantity generated by the movement of the measuring subject from the heart rate measured by the first measuring unit 101.The second operation unit 104 changes the depth of the subject body temperature from the amount of heat obtained by the first operation unit 103 and the amount of heat exchanged between the subject and the subject measured from the temperature measured by the second measuring part 102 at the time t and the amount of evaporation of the sweat obtained from the perspiration amount of the measurement subject Presumption.Diagram【課題】深部温度をより容易に推定する深部体温推定装置を提供する。【解決手段】第１測定部１０１は、測定対象者の心拍数を測定する。第２測定部１０２は、測定対象者の雰囲気の気温を測定する。第１演算部１０３は、第１測定部１０１が測定した心拍数より測定対象者の運動により発生する熱量を求める。第２演算部１０４は、時刻ｔにおいて第１演算部１０３が求めた熱量と、第２測定部１０２が測定した気温から求められる測定対象者の雰囲気と測定対象者との間の熱交換量と、測定対象者の発汗量より求める汗の蒸発量とから測定対象者の深部体温の変化を推定する。【選択図】図１
