PROBLEM TO BE SOLVED: To secure image display regions when media interfering sound waves exist near the probe of an ultrasonograph. SOLUTION: The ultrasonograph has an ultrasonic probe 31 having a plurality of vibrators arrayed therein, an ultrasonic wave transmitting/receiving means 33 which transmits or receives ultrasonic waves by driving the vibrator according to a specified drive method, a means 34 for processing and displaying signals obtained by a transmitting/receiving circuit, a sensor 32 mounted on a sound wave radiation surface of the ultrasonic probe, a detection means 36 for detecting the range in which the sound wave radiation surface contacting the surface of the medium to be examined by outputs of the sensor and a scanning control means 15 which controls the transmission or reception of ultrasonic waves based on signals from the detection means.
