Abstract
An ultrasonic measurement method includes irradiating an object to be measured with an ultrasonic wave, acquiring a reflection wave from the object, calculating at a processor an acoustic impedance in a depth direction of the object from the reflection wave, and estimating and outputting a thickness of the object based upon an inflection point determined by second-order differentiation of the acoustic impedance.
