Abstract
An internal temperature measurement device includes a sound wave sensor that transmits a sound wave to a subject and receives a reflected sound wave reflected by the subject, a time measurement device that measures an elapsed time elapsed between transmission of the sound wave from the sound wave sensor and reception of the reflected sound wave, a sound velocity calculator that calculates a sound velocity in the subject according to the elapsed time measured by the time measurement device, and an internal temperature derivation device that determines an internal temperature of the subject according to the sound velocity calculated by the sound velocity calculator.
