Abstract: PURPOSE:To reduce the extent of a fact that a continuous wave transmitting signal is leaked into an ultrasonic wave echo receiving circuit as well as to secure a good signal-to-noise ratio by installing a lot of pulse vibrators and continuous wave vibrators separately in a probe and also installing a pulse wave transmitting circuit, driving these pulse vibrations, and a continuous wave transmitting circuit driving these continuous wave vibrations separately. CONSTITUTION:As a means to separate a pulse wave transmitting circuit 20 from a continuous wave transmitting circuit 30, for example, it is considered to set the circuit 30 and the circuit 20 to each of separate substrates and shield them electrically. In addition, the circuit 20 and the circuit 30 both have no part for contact other than a probe end, whereby a selector switch or the like is no longer required so that the said separation can be done easily. They are made contact with each other by a control circuit 9, but there is no problem of a noise as to any leakage or the like of a continuous wave transmitting signal. With this constitution, the leakage of the transmitting signal of a continuous wave ultrasonic wave into an ultrasonic wave echo receiving wave phasing circuit 5 becomes reduced, saturation in an amplifier of this ultrasonic receiving wave phasing circuit 5 will not come to occur so that a signal-to-noise ratio comes so good.
