An ultrasonic diagnostic apparatus for recognition helpful to diagnosis by giving and displaying a score serving as an index of diagnosis.An ultrasonic diagnostic apparatus comprises a displacement measuring section (109) for measuring the displacement of an organism tissue of a subject (100) according to a reflection echo signal received correspondingly when an ultrasonic wave is transmitted from a probe (101) to the subject (100), an elastic image creating section for creating an elastic image after determining the distortion amount or the elastic modulus from the displacement, and an image display (107) for displaying the elastic image.The ultrasonic diagnostic apparatus further comprises scoring means for specifying the distorted state or elastic state according to the information on the elastic image outputted from the elastic image creating section.
