<P>PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detector and an ultrasonic flaw detection method which can improve inspection reliability while suppressing device cost. <P>SOLUTION: A scanning part 21 brings an arrangement row of vibrators 6 of a flaw detection probe 5 in contact with a flaw detection surface of a test object 3 through spacers 9 and supports the flaw detection probe 5 movably in a direction. At each phase (each position of a flaw detection probe) in moving scan of the scanning part 21 (scanning step), electronic scan is performed based on multiple delay patterns obtained by combining respective curvatures of the arrangement row of the vibrators 6 of the flaw detection probe 5, and respective intervals between the arrangement row of the vibrators 6 of the flaw detection probe 5 and the flaw detection surface of the test object 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
