1. An ultrasonic device, comprising:
an ultrasonic sensor that applies ultrasound to a test object;
a casing that holds the ultrasonic sensor to be immersed in a contact medium that allows the ultrasound to propagate therethrough, the casing including a test object-facing opening; and
circuitry configured to, when the test object-facing opening of the casing is passing an opening of the test object in a test direction of the test object, control a moving speed of the casing such that a region of contact between the test object and the contact medium entering the opening of the test object is kept within the opening of the test object.
