An ultrasonic diagnostic apparatus is characterized by including a displacement/strain calculation unit 12 which obtains a strain distribution of a body site on a scan plane when pressed by an ultrasonic probe 1 and a non-pressed image creation unit 5 which corrects an ultrasonic image on the basis of the strain distribution calculated by the displacement/strain calculation unit and generates a corrected ultrasonic image in a non-pressed state or a pressed image creation unit 40 which generates a corrected reference image obtained by adding, to the reference image, a strain equivalent to one in the ultrasonic image on the basis of the strain distribution obtained by the displacement/strain calculation unit 12, in order to accurately perform comparative observation of an ultrasonic image and a reference image captured by a medical diagnostic apparatus other than the ultrasonic diagnostic apparatus.
