Claim 0:
1. An ultrasonic flaw detection device, comprising:
an ultrasonic probe that emits ultrasonic waves to an inspection object and detects reflected waves;
a sheet material attached to a surface of the inspection object and having two-dimensional patterns shown thereon, the two-dimensional patterns being arranged on the inspection object and indicating positions on the inspection object;
an imaging device attached to the ultrasonic probe and imaging the two-dimensional patterns; and
a processing unit that reads position information indicating a position on the inspection object from a captured image captured by the imaging device and relates a detection result of the ultrasonic probe to the position information, wherein
the processing unit determines an index indicating a degree of quality of the detection result based on an air pocket area that is an area in which air pockets are shown in a predetermined area of the captured image.
