PROBLEM TO BE SOLVED: To provide a contact internal thermometer capable of reducing a measurement error caused by the attitude thereof.SOLUTION: A contact internal thermometer 100 comprises: a first temperature sensor 32 thermally connected to a first probe 30 which comes into contact with a measured surface of a measuring object; a second temperature sensor 33 thermally connected to a second probe 31 which comes into contact with the measured surface of the measuring object; a first environmental temperature sensor 34; a second environmental temperature sensor 35; a flow passage partition 21 for partitioning a first heat flow passage heading from the first temperature sensor 32 to the first environmental temperature sensor 34 and a second heat flow passage heading from the second temperature sensor 33 to the second environmental temperature sensor 35; and a controller 50 which calculates the internal temperature of the measuring object on the basis of the temperatures detected by the first temperature sensor 32, the second temperature sensor 33, the first environmental temperature sensor 34, and the second environmental temperature sensor 35. The direction of the first heat flow passage differs from the direction of the second heat flow passage. |
