An ultrasonic diagnostic apparatus comprises a first reception echo obtaining unit, a second reception echo obtaining unit, a reception echo combining unit, and an image generating unit. The first reception echo obtaining unit transmits a plurality of ultrasonic pulses having frequency spectra different from one another to an object, and obtains each of reception echoes corresponding to the plurality of ultrasonic pulses. The second reception echo obtaining unit transmits an ultrasonic pulse having the same frequency component characteristics as an combined pulse obtained by combining the plurality of ultrasonic pulses, and to obtain an reception echo. The reception echo combining unit combines the reception echoes obtained by the first reception echo obtaining unit and the reception echo obtained by the second reception echo obtaining unit to generate a combined signal. The image generating unit generates an image of echoes reflected from the object on the basis of the combined signal.
