In order to properly discern a plurality of streams of blood flow having different contrast agent arrival times or blood concentration properties, an ultrasonic diagnostic apparatus 200 comprises: an ultrasonic probe 1; a transceiver section 2; a quadrature detector section 3; a power calculating section 4 for calculating the power P of blood flow; a power peak holding section 21 for comparing the latest power P and a predecessor peak value Po, and outputting the larger one as a peak value P′ and an elapsed time t′ corresponding to the peak value P′; a predecessor power/elapsed time keeping section 22 for keeping the predecessor peak value Po and the corresponding elapsed time ‘to’ and outputting these values to the power peak holding section 21; a timer 11 for measuring an elapsed time t from a reference time; a blood flow image producing section 25 for producing a power peak hold blood flow image G2 in which the hue is changed before and after the elapsed time t′ reaches a hue change time tc and the brightness varies depending upon the peak value P′; an operating section 12 for resetting the timer 11 and specifying the hue change time tc; and a display 6. For example, blood flow passing through the hepatic artery and that passing through the portal vein can be displayed in different colors.
