PURPOSE:To safely perform the ultrasonic observation and the diagnosis by providing a characteristic output means for outputting a driving characteristic of an ultrasonic vibrator on a probe, and providing a display means for displaying radiation power of the ultrasonic vibrator by a characteristic output of the characteristic output means. CONSTITUTION:A voltage control circuit 5 varies a voltage inputted from a transmitting power source 9 by a variable resistor 4, and outputs it to a transmitting pulser 3. To a control terminal of the transmitting pulser 3, a transmission timing pulse is inputted from a transmission control circuit 10, and the transmitting pulser 3 boosts a voltage inputted from the control circuit 5 and impresses it to a vibrator 2 by synchronizing with the transmission timing pulse. From the vibrator 2, an ultrasonic pulse wave is emitted to the part to be examined, etc. To an A/D converter 6, the same voltage as the voltage inputted to the transmitting pulser 3 is inputted and this voltage is converted to a digital value and outputted to a V-R converting ROM 7. The V-R converting ROM 7 outputs the inputted digital value as an address to a display circuit 8. The display circuit 8 converts the inputted data to a video signal and outputs it to a display device 11.
