An ultrasonic diagnostic apparatus by which IMT (intima media thickness) examination can be efficiently performed by simple processing in a health check. The ultrasonic diagnostic apparatus includes: a signal processing unit (28) for performing at least envelope detection processing on reception signals outputted from an ultrasonic probe (100) to generate envelope data an image data generating unit (30) for generating image data representing an ultrasonic image on an object to be inspected based on the envelope data a pre-measurement processing part (312) for performing structural image generating processing on the envelope data and a measurement part (313) for performing measurement based on the envelope data processed by the pre-measurement processing part (312).
