摘要：The invention is directed to an ultrasonic inspection method, an ultrasonic testmethod, and an ultrasonic inspection apparatus that enable sizing to be executed even
for a minute defect using an ultrasonic wave. A holder holds a transmitting probe forexecuting an angle beam method and a receiving probe for executing a vertical beammethod. A motor and a guide rail form a movement mechanism for the transmittingprobe and the receiving probe. In an ultrasonic test mode, the transmitting probeexecutes the angle beam method and transmits and receives an ultrasonic wave. In asizing mode, the transmitting probe transmits an ultrasonic wave and the receiving probereceives this wave. A tip echo of a wave diffracted from a tip of a defect on a sample and acorner echo reflected from a corner of the defect are measured from a waveformreceived by the receiving probe.
