An ultrasonic diagnostic apparatus having a function of obtaining a tomographic image and an elastic image is adaptable to not only a close examination mode, but also a screening mode, and obtains an elastic image suitable for each examination purpose. Accordingly, the ultrasonic diagnostic apparatus of the present invention comprises tomographic image acquisition means for transmitting an ultrasonic wave from a probe to a body being examined, and receiving a reflection echo signal corresponding to the transmission of the ultrasonic wave to obtain a tomographic image, elastic image acquisition means having a first acquisition mode for determining a tissue elasticity amount of a biomedical tissue of the body being examined on the basis of the reflection echo signal to obtain an elastic image, and display means for displaying at least the elastic image. The elastic image acquisition means has a second acquisition mode different from the first acquisition mode.
