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; an environmental temperature sensor 34; 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, and the environmental temperature sensor 34. When the rotation angle between at least two different measurement attitudes is &thetas;, the environmental temperature sensor 34 is arranged on the surface which passes a rotating shaft when the measurement attitude changes and forms an angle &thetas;/2 with respect to a vertical plane. |
