Summary: | PROBLEM TO BE SOLVED: To provide an ultrasonic measurement apparatus capable of outputting information concerning strains in a plurality of directions as well as information of displacement and strain in one direction of an object to be measured. SOLUTION: This ultrasonic measurement apparatus is provided with first and second ultrasonic probes. An information acquisition section acquires information concerning whether a force applied to the object to be measured or a time change in displacements of the object to be measured is an increase period or a decrease period. The first ultrasonic probe receives ultrasonic waves reflected by the object to be measured located at an overlapped part of ultrasonic transmission areas of the two probes and generates first receiving data. The second ultrasonic probe similarly generates second receiving data. An arithmetic processing section calculates first displacement related information concerning a first direction of the object to be measured by using data in either one period out of the increase period and the decrease period, among first received data, and calculates second displacement related information concerning a second direction of the object to be measured by using data in the same period as that used to calculate the first displacement related information, among second received data.
