The present invention provides an ultrasonic diagnostic apparatus that is capable of displaying an elastic image, enabling an accurate and easy identification of tissue characteristics of a diagnostic part. Elasticity data regarding a test object is obtained based on a received signal of an ultrasonic probe, and an elastic image representing a distribution of the elasticity data of the test object is generated. A display mode setting means sets a display mode of the elastic image in such a manner that a different tissue can be identified based on a value of the elasticity data. In this case, the display mode is differentiated by the value of the elasticity data within one tissue. With this configuration, the tissue characteristics of the diagnostic part are identified by the elasticity data, and displayed in a different display mode, thereby displaying an elastic image identifiable accurately and easily.
