An ultrasonic diagnostic apparatus includes an ultrasonic transmission/reception unit and an image generating unit. The ultrasonic transmission/reception unit transmits a first ultrasonic pulse having a maximum amplitude in a positive pressure, a second ultrasonic pulse having a maximum amplitude in a negative pressure and a third ultrasonic pulse derived by compounding the first ultrasonic pulse with the second ultrasonic pulse into an object in which a contrast medium is injected and obtains first, second and third reception echoes corresponding to the first, second and third ultrasonic pulses respectively. The image generating unit generates a compounded signal which is a nonlinear component from the contrast medium by a linear calculation of the first, second and third reception echoes and generates image data of the object by using the compounded signal.
