An ultrasonic transmit-receive probe is disclosed which is capable of effectively protecting an internal structure of the probe against leaked steam so as to ensure stable and positive operation of the probe over a long period of time. The probe includes an enclosing tube arranged in a probe housing. The enclosing tube is sealedly connected at one end thereof to an oscillator housing receiving an oscillator therein to communicate therewith and sealedly fitted at the other end thereof on a plug received in the other end of the probe housing so as to outwardly project therefrom, thereby sealedly protecting the oscillator and plug against the atmosphere in the probe housing.
