1. An ultrasonic testing device that performs flaw detection on a test object having an inner circumferential surface of a substantially rectangular shape closed in a transverse section, the ultrasonic testing device comprising:
a shoe configured to be in contact with one corner of the inner circumferential surface of the test object;
an ultrasonic array configured to be fixed to the shoe to define, together with the shoe and the one corner, a medium space in which a contact medium used for propagating an ultrasonic wave is enclosed, and configured to transmit an ultrasonic wave to the one corner and receive a reflected ultrasonic wave; and
a forcing unit configured to be in contact with a diagonal corner of the one corner and push the shoe against the one corner.
