PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus capable of simply displaying the elastic image of bio-tissue with high precision. SOLUTION: The ultrasonic diagnostic apparatus 100 is constituted so as to measure the displacement direction of the bio-tissue of a reference region separately set with respect to the display region of a diagnostic image by a displacement measuring part 11 to output the time phase data of a heart rate on the basis of the displacement direction measured by an elastic data operation part 13. Further, the ultrasonic diagnostic apparatus 100 is constituted so as not only to calculate a strain value by an elastic data operation part 13 but also to calculate the pressure value acting across elastic frame data on the basis of the pressure value of a diagnostic region measured by a pressure measuring part 12 to calculate the quantitative elastic value such as the Young's modulus on the like using these calculated strain value and pressure value. Furthermore, the ultrasonic diagnostic apparatus 100 is constituted so as to display the elastic value and the time phase data on an image display part 9 in a discriminable state along with the diagnostic image by an elastic image constituting part 14 and a time phase data display part 17.
