PROBLEM TO BE SOLVED: To provide an ultrasonic flaw inspection device capable of easily discriminating the reflected wave from a flaw, and to provide an ultrasonic flaw inspection method. SOLUTION: The ultrasonic flaw inspection device has an ultrasonic probe 101 comprising a piezoelectric element, a transmission and reception part 6 for transmitting an ultrasonic wave from ultrasonic probe 101 and receiving the ultrasonic wave by the ultrasonic probe 101 and a display part 9 for displaying the ultrasonic signal received in the transmission and reception part 6. At least a part of the ultrasonic probe 101 is immersed in a liquid to transmit the ultrasonic wave to inspect a solid inspection target such as a metal or the like. The ultrasonic probe 101 is arranged to the surface of the inspection target 102 at an angleθ2 producing a surface wave on the surface of the inspection target 102. A scanning mechanism 7 scans the ultrasonic probe 101 in the direction of the angleθ2. COPYRIGHT: (C)2009,JPO&INPIT
