An ultrasonic diagnosis apparatus comprising: an ultrasonic probe which includes a plurality of ultrasonic transducers which transmit ultrasonic waves to an object, receive the ultrasonic waves reflected by the object, and output ultrasonic detection signals; a reception time calculating device which calculates at least one of a reception time and a reception wave at each of elements corresponding to lattice points set in a shallower region than a region of interest in the object; an image generating device which generates an image at a lattice point in the region of interest, based on a hypothetical sound velocity set in the region of interest and the calculated one of the reception time and the reception wave; an image analyzing device which analyzes the generated image; and a local sound velocity calculating device which calculates a local sound velocity in the region of interest, based on a result of the image analysis.
