Zusammenfassung:An ultrasonic flaw detecting apparatus including: a transducer including a piezoelectric element array for transmitting ultrasonic waves to and receiving echo signals from a test object; an element driving unit for scanning the piezoelectric element array at a predetermined cycle and generating the ultrasonic waves; a synthesizing unit for synthesizing an internal image of the test object based on the echo signals received by the piezoelectric element array; and a signal replacing unit for replacing the received echo signal with an echo signal in which a bottom echo of the test object is removed.
