PROBLEM TO BE SOLVED: To provide a probe unit for an ultrasonic flaw detector which inspects satisfactorily a defective part, without using a "single reflection method", even when the defective part to be subjected to ultrasonic flaw detection exists as a surface crack of an inspected object and even when an obstacle exists on a face, and also to provide a method of estimating a crack depth by an ultrasonic flaw detection method. SOLUTION: The probe unit 1 for the ultrasonic flaw detector is provided with a transmitting probe 1a and a receiving probe 1b, and the transmitting probe 1a is arranged in the probe unit 1 to incline a sound axis 2a to a receiving probe 1b side. This method of estimating the crack depth by the ultrasonic flaw detection method uses the probe unit 1. COPYRIGHT: (C)2007,JPO&INPIT
