摘要：
An ultrasonic measurement apparatus (1) estimates a property/state of a test object (100) that allows an injected ultrasonic wave to propagate as plate waves (UW) of propagation modes. The ultrasonic measurement apparatus (1) includes: a receiver (30) configured to receive a detected signal obtained by detecting the plate waves (UW) propagating through the test object (100) to output a received signal indicating a time-domain waveform of the detected signal; an intensity detector (12) configured to detect the signal intensity of a waveform part corresponding to a first propagation mode, and the signal intensity of a waveform part corresponding to a second propagation mode; and an estimator (13) configured to make a comparison between the signal intensities to estimate a property/state of the test object (100) on the basis of a result of the comparison.
