An ultrasonic diagnostic apparatus in which moving images of rapidly moving tissues and organs can be preferably displayed in real time and the lower power consumption can be achieved. The apparatus includes an ultrasonic probe including plural ultrasonic transducers for transmitting ultrasonic waves toward an object to be inspected according to drive signals and receiving ultrasonic echoes propagating from the object to output reception signals, an image generating unit for supplying the drive signals to the ultrasonic probe and processing the reception signals outputted from the ultrasonic probe to generate image signals representing ultrasonic images, and a display unit including a display of an impulse drive type for displaying the ultrasonic images based on the image signals generated by the image generating unit.
