An ultrasonic diagnostic apparatus enabling accurate measurement of elasticity information is provided. The ultrasonic diagnostic apparatus is characterized in comprising setting means configured to set a first movement reference point and a second movement reference point ON a tomographic image and/or an elastic image, and measurement means configured to cause the first movement reference point and the second movement reference point to follow the pulsation of an object and to measure the length of a line segment formed by the first movement reference point and the second movement reference point, and causes display means to display the length of the line segment and elasticity information based ON the strain and/or elastic modulus.
