PROBLEM TO BE SOLVED: To provide a body temperature measuring device that enables a reliable and accurate measurement temperature and acquires body temperature variations with a high degree of precision while suppressing battery consumption.SOLUTION: In measuring a skin temperature of a body by a skin temperature sensor, an actual measurement start time point and a measurement time are set； from a predetermined time before the set actual measurement start time point is reached, temperature measurement is executed by the skin temperature sensor at a first time interval； on at least any one condition of the conditions that the skin temperature reaches a first condition value, an increase change rate in the skin temperature reaches a second condition value, and a temperature difference between a proper skin temperature and an external temperature reaches a third condition value, the skin temperature sensor or the skin temperature sensor and an external temperature sensor are caused to measure a temperature at a second time interval； and the measured temperature data is stored in association with a measurement date.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】バッテリ消費を抑え、確実かつ正確な測定温度を可能とし、高精度に体温変動を得る体温測定装置を提供する。【解決手段】皮膚温度センサにより身体の皮膚温度を測定するに際して、実測開始時刻及び測定時間を設定させ、設定された実測開始時刻に達する所定時間前より第１の時間間隔で皮膚温度センサにより温度測定させ、皮膚温度が第１の条件値に達し、若しくは皮膚温度の上昇変化率が第２の条件値に達し、さらに適宜皮膚温度と外部温度との温度差が第３の条件値に達したときの少なくとも何れかの条件で当該皮膚温度センサ、又は、皮膚温度センサ及び外部温度センサに対して第２の時間間隔で温度測定させて測定した温度データに測定日時を対応付けて記憶させる構成とする。【選択図】図４
