Claims

[Scope of utility model registration request]

In an ultrasonic probe device, a surface having a first angle that allows a predetermined refraction angle to be obtained in the test material with respect to the flaw detection surface of the test material, and a direction perpendicular to the surface having the first angle. An ultrasonic probe device comprising: a surface having a second angle such that ultrasonic waves are incident approximately perpendicularly to the inclined defect;
