In one aspect of the present invention, an object is to provide an ultrasonic diagnostic device that simultaneously displays an IMT and the elastic indices of a blood vessel to accurately determine, through composite observations, the risk for developing arteriosclerosis. According to one aspect of the present invention, there is provided an ultrasonic diagnostic device including: an ultrasonic probe that transmits ultrasound to a body under test and that receives ultrasonic echo reflected of the body under test to output a reception signal; image data generation means that generates, based on the reception signal output from the ultrasonic probe, image data representing an ultrasonic image on a blood vessel of the body under test; IMT measurement means that measures, based on the image data generated by the image data generation means, an IMT (intima media thickness) of the blood vessel; elastic index measurement means that determines, based on the image data generated by the image data generation means, a value representing an elastic index of the blood vessel; and display means that displays a two-dimensional coordinate system in which the IMT is represented on a first coordinate axis and the value representing the elastic index of the blood vessel is represented on a second coordinate axis.
