An ultrasonic diagnostic apparatus characterized by comprising: an ultrasonic probe for transmitting/receiving an ultrasonic wave to/from an object; a phasing and summing unit for generating RF signal frame data of a cross-sectional site of the object on the basis of a reflection echo signal measured by the ultrasonic probe; an elasticity calculator for generating frame data of elasticity information representing the degree of hardness or softness of a tissue at each measurement point of the cross-sectional site on the basis of a pair of RF signal frame data acquired in different times; a weighting unit for weighting the elasticity information of each measurement point of the generated elasticity frame data in accordance with the degree of sharpness of a distribution of elasticity information for plural measurement points containing adjacent measurement points; a smoothing unit for smoothing the weighted elasticity information of the plurality of elasticity frame data generated at the different times; and an elasticity image display unit for generating an elasticity image on the basis of the smoothed elasticity frame data and displaying the generated elasticity image on a display unit.
