An ultrasound diagnostic apparatus that transmits a push pulse for focusing ultrasonic waves on a specific part of a subject to physically press tissues using an ultrasound probe, repeatedly transmits and receives the ultrasonic waves to and from the subject, and detects a propagation state of shear waves in a region of interest, includes: a push pulse transmission unit that transmits the push pulse a displacement detection unit that transmits detection waves to the subject, receives reflected detection waves, generates a plurality of received signals in time series, and detects displacement of the tissues an elasticity measurement unit that analyzes the propagation state of the shear waves and measures elasticity of each tissue a probe movement detection unit that detects a moving speed of the ultrasound probe a sequence holding unit that holds a plurality of operation sequences and a sequence selection unit that selects one operation sequence.
