An ultrasonic diagnostic apparatus includes: a contrast image creating device which transmits each of contrast imaging transmission pulses and creates a contrast image, based on a received signal corresponding contrast imaging transmission pulse; a first reference image creating device which creates a reference image using the received signal corresponding to the contrast imaging transmission pulse; a second reference image creating device which transmits a reference transmission pulse different in frequency from the contrast imaging transmission pulse and creates a reference image, based on a received signal corresponding to the reference transmission pulse; a switching device which selects one of the first reference image creating device and the second reference image creating device and activates the same; and an image display device which displays the contrast image and the reference image side by side or displays the same in superimposed form.
