PROBLEM TO BE SOLVED: To provide a technique which, in the case of acquiring information on a portion to be inspected by using an acoustic medium accommodated between a portion to be inspected and a portion-to-be-inspected holding part, prevents the acoustic medium from being leaked to the outside.SOLUTION: A device for acquiring information on a portion to be inspected comprises a portion-to-be-inspected contact part 93 which can be deformed corresponding to the shape of the portion to be inspected 1 and brought into contact between the portion to be inspected 1 and a portion-to-be-inspected holding part 11. While keeping a sealed space constituted by the portion to be inspected 1, the portion-to-be-inspected contact part 93, and the portion-to-be-inspected holding part 11 in a state of negative pressure lower than the atmospheric pressure to keep the portion to be inspected 1 in close contact with the portion-to-be-inspected contact part 93, pressure adjusting means 91 accommodates an acoustic medium 12 in the sealed space.SELECTED DRAWING: Figure 2 |
