Abstract
An ultrasonic transmission medium is received in a medium container, and an opening of the container is sealed by a polymer membrane. An inspection object is received in an inspection object receiving container body that is separate from the medium container and whose opening is formed opposite the polymer membrane of the medium container. The opening of the inspection object receiving container body is covered by the polymer membrane of the medium container, and a measurement environment space formed by a frame body, the polymer membrane, and the inspection object is reduced in pressure to cause the polymer membrane to be in intimate contact with the inspection object. Then, flaw detection is performed by emitting and applying an ultrasonic wave from an ultrasonic probe to the inspection object via the ultrasonic transmission medium and the polymer membrane.
