PROBLEM TO BE SOLVED: To provide an ultrasonic image diagnostic device capable of preventing a push pulse from being transmitted to a region which may not be imaged correctly.SOLUTION: An ultrasonic image diagnostic device includes a target setting part which sets a target position for performing push pulse irradiation from an ultrasonic probe on an ultrasonic image, an image determination part which determines a non-propagation region where a shear wave is difficult to propagate with the ultrasonic image to acquire it, and an image generation part which generates an image for presenting the non-propagation region together with the ultrasonic image.
