Disclosed in an ultrasonic diagnostic apparatus for appropriately evaluating the image quality of a elastic image with high reliability and accuracy, the ultrasonic diagnostic apparatus including: a probe (12) that transmits and receives ultrasonic waves to and from an object; an elasticity information calculating unit (32) that calculates elasticity information on the basis of the ultrasonic waves received by the probe (12); an elastic image constructing unit (34) that generates an elastic image on the basis of the elasticity information; an image display device (display) (26) that displays the elastic image; and an elastic image evaluating unit (40) that detects the fluctuation cycles in the elasticity information, finds the fluctuation patterns in the elasticity information for each predetermined section in the fluctuation cycles, and evaluates the stability of the elastic image on the basis of the fluctuation patterns.
