An ultrasonic measurement apparatus comprising: a plurality of ultrasonic probes that include, at least, a first ultrasonic probe which has an ultrasonic wave transmitting area and is configured to transmit an ultrasonic wave to an object to be measured and receive an ultrasonic wave reflected by the object to be measured and produce first received data, and a second ultrasonic probe which has an ultrasonic wave transmitting area and is configured to transmit an ultrasonic wave to the object to be measured and receive an ultrasonic wave reflected by the object to be measured and produce second received data, wherein the first and second ultrasonic probes are arranged in such a manner that their acoustic axes cross each other and their ultrasonic wave transmitting areas overlap each other, the object to be measured being located in the overlapped area; an information acquisition unit configured to acquire information throughout time on whether a current period is an increase period or a decrease period, the increase period being a period in which a temporal change of a force applied to the object to be measured or an amount of deformation of the object to be measured indicates a tendency of increase, the decrease period being a period in which the temporal change of the force or the amount of deformation indicates a tendency of decrease; a transmitting circuit configured to input signals for transmitting ultrasonic waves to the first and second ultrasonic probes (1010, 1020); a receiving circuit configured to receive signals produced by the first and second ultrasonic probes (1010, 1020) upon reception of ultrasonic waves; a processing unit; an output unit; and a system control unit configured to control the transmitting circuit, the receiving circuit, the processing unit, and the output unit; wherein the first and second ultrasonic probes are configured to receive at different time points and to transmit at different time points; the processing unit is configured to calculate first displacement related information concerning a first direction of the object to be measured by using data in either one of the increase period and the decrease period among the first received data, and calculate 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 the second received data, wherein the data in the same period among the second received data has been acquired at a different time point within the same period than the data in the same period among the first received data; and the output unit is configured to output information on the object to be measured by using the first and second displacement related information. a plurality of ultrasonic probes that include, at least, a first ultrasonic probe which has an ultrasonic wave transmitting area and is configured to transmit an ultrasonic wave to an object to be measured and receive an ultrasonic wave reflected by the object to be measured and produce first received data, and a second ultrasonic probe which has an ultrasonic wave transmitting area and is configured to transmit an ultrasonic wave to the object to be measured and receive an ultrasonic wave reflected by the object to be measured and produce second received data, wherein the first and second ultrasonic probes are arranged in such a manner that their acoustic axes cross each other and their ultrasonic wave transmitting areas overlap each other, the object to be measured being located in the overlapped area;
