An ultrasonic diagnostic apparatus includes: a transmitting section for generating first, second and third drive signals to drive an ultrasonic probe a receiving section for getting echoes, produced by reflection of the ultrasonic waves responsive to those drive signals and generating first, second and third received echo signals a storage section to store the first received echo signal an adjusting section for defining intense and faint echo regions within a measuring range for the first received echo signal based on a stored feature quantity and for determining the second and third gains based on the feature quantities in the intense and faint echo regions a displacement measuring section for measuring the magnitudes of displacement in the echo regions based on the second and third received echo signals and a qualitative value calculating section for calculating the attribute property value of the subject based on the magnitudes of displacement.
