PROBLEM TO BE SOLVED: To improve accuracy in measuring a temperature at a deep portion.SOLUTION: A temperature measurement device includes a temperature measurement unit 43, an arithmetic logical unit 74, and a control unit 73 for controlling operations of the temperature measurement unit and the arithmetic logical unit. The temperature measurement unit 43 includes: a base material 40 having a first surface which is a surface contacting with an object to be measured, and a second surface which faces the first surface and is a surface on the surroundings side; a first temperature sensor 50; a second temperature sensor 52; a surrounding temperature acquisition unit 53; and a heat flow control unit 61 provided on the second surface which is the surface of the base material 40 on the surroundings side. The heat flow control unit 61 performs heat exchange with the surroundings so as to make a temperature on the second surface of the base material come closer to a temperature of the surroundings, compared with the case where the heat flow control unit is absent. The first temperature sensor 50 and the second temperature sensor 52 perform multiple measurements of a first temperature and a second temperature, respectively, under the conditions that a third temperature is different. The arithmetic logical unit 74 calculates a deep portion temperature Tc in a deep portion of the object to be measured, on the basis of an operation expression for the deep portion temperature. |
