PROBLEM TO BE SOLVED: To provide a high temperature distortion measuring instrument for measuring distortion and stress of a high temperature apparatus such as a boiler or a turbine using a Wheatstone bridge circuit. SOLUTION: This high temperature distortion measuring instrument measures the distortion using the Wheatstone bridge circuit, and comprises a measuring apparatus for individually measuring resistances of two resistors built in a high temperature sensor part and a resistance change rate converter for calculating a resistance charge rate using a conversion value from the resistances.
