Claim One:
1. A method for measuring an internal temperature of a freezing target object, the method comprising: a placing step of placing the freezing target object in a microwave resonating magnetic field generated by a microwave resonator; a state detection step of detecting a resonant state of the freezing target object in a frozen state by using the microwave resonator; a temperature calculation step of calculating the internal temperature of the freezing target object in the frozen state by at least applying a resonance peak voltage obtained from the resonant state detected in the state detection step to a calibration curve calculated by performing a regression analysis in which the internal temperature of the freezing target object is a response variable and a resonance peak voltage of an inspection target object whose constituent is the same as the freezing target object is included as an explanatory variable, the resonance peak voltage of the inspection target object being detected using the microwave resonator.
