An ultrasonic diagnostic apparatus according to the present invention includes: a transmitting section 102 that drives an ultrasonic probe to transmit an ultrasonic wave toward a measuring region of a subject including an arterial vascular wall; a receiving section 101 that receives a reflected wave, produced by getting the ultrasonic wave reflected by the subject, at the ultrasonic probe to generate a received signal; a movement information deriving section 110 for deriving information about at least the axial movement of the arterial vascular wall based on the received signal; and a boundary locating section 109 for locating at least one of the blood flow-intima boundary, the media-adventitia boundary and the adventitia-body's connective tissue boundary of the arterial vascular wall in the measuring region based on the movement information.
