<p>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; and a surrounding temperature acquisition unit 53. 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, by using the measured temperatures and on the basis of an operation expression for the deep portion temperature.</p> |
