摘要

An ultrasonic flaw detection jig comprises a base that is brought into contact with a probe of an ultrasonic flaw detecting device, and a projection that is provided on the base and is inserted into a testing hole provided in a test object. The testing hole comprises a conical section that connects to the main face of the test object at one end and extends from the main face so that the diameter decreases, and a connecting section that connects the bottom of the conical section and the back face of the test object. The projection has a conical shape corresponding to the shape of the conical section.
