An ultrasonic measurement device includes an ultrasonic probe having a plurality of ultrasonic elements arranged, each of the ultrasonic elements being adapted to transmit and receive an ultrasonic beam, and an arithmetic processor adapted to perform a reduction process of reducing an amount of information of received signals received by the respective ultrasonic elements based on a reception frequency, then perform a beam forming process on the signals, on which the reduction process has been performed, to generate an ultrasonic image.
