A temperature measurement device includes a temperature measurement part, a calculation part, and a control part for controlling the operation of the temperature measurement part and the calculation part. The temperature measurement part has a substrate having a first surface as a contact surface with a measured body, and a second surface as an environment-lateral surface which is opposite the first surface, a first temperature sensor, a second temperature sensor, and a third temperature sensor, and the first temperature sensor. The second temperature sensor, and the third temperature sensor measure a first temperature, a second temperature, and a third temperature a plurality of times under conditions in which the temperature of the environment varies, and the calculation part calculates a deep temperature in a deep part of the measured body by using the measured temperatures. |
