PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detection testing method capable of easily and accurately detecting the flaw of the heat influence part formed to the periphery of the boundary part in a welding place. SOLUTION: A probe 110 constituted of a plurality of vibrators 113 is arranged on the flaw detection surface 201 of a specimen 200 and the angleθ<SB>1</SB>of refraction of the ultrasonic waves transmitted from the probe 110 to be introduced into the specimen 200 from the flaw detection surface 201 is adjusted so as to be received by at least a part of a plurality of the vibrators 113 of the probe 110 corresponding to the magnitudes of the bevel anglesϕ1 andϕ2 of the boundary parts 204 and 205 of the welded place 203.
