PROBLEM TO BE SOLVED: To solve problems with an ultrasonograph sequentially receiving ultrasonic waves irradiated from one or a plurality of ultrasonic vibrators and displaying with a display, including the inability to clearly display the shape or the like of an affected site, providing only blurred images. SOLUTION: A second ultrasonic vibrator 4 is arranged at a prescribed angle with respect to the irradiation direction of ultrasonic waves from a first ultrasonic vibrator 1, and an affected site 3 of a human body is irradiated with ultrasonic waves of a second frequency f2 from the second ultrasonic vibrator 4. An A/D converter 6 is connected to the first ultrasonic vibrator 1, the output of the A/D converter 6 is connected to a difference signal output circuit 7, a sum signal output circuit 8, a harmonic signal output circuit 9, and a frequency division signal output circuit 10. The output of the difference signal output circuit 7, the sum signal output circuit 8, the high harmonic signal output circuit 9 and the frequency dividing signal output signal circuit 10 is connected to a storage circuit 11. The output of the storage circuit 11 is connected to an image signal conversion circuit 12, and the output of the image signal conversion circuit is connected to a display circuit 13.
