Problems SolvedThe information solves the problem of how to provide a structure and a manufacturing method that can inexpensively and stably obtain a scattered X-ray eliminating grid wherein air serves as an intermediate substance even as X-ray absorbing substance parts are accurately positioned and held. SolutionThe invention includes disposing guide slit plate mechanisms fixed relative to one another, namely, parallel to and spaced apart from one another by a prescribed distance; fitting metal foils, which serve as X-ray absorbing substance provided between the guide slit plate mechanisms, parallel to primary X-rays; inserting both ends of the metal foils into the guide slit plate mechanisms; inserting, when applying tension evenly, a rod, which is sheathed in an elastic body, into holes formed in the metal foils on the tip sides of the metal foils beyond the inserted portions; and adopting a structure that ensures that the cross sectional shape of the elastic body sheathing the rod has a sufficient wall thickness in a direction in which the elastic body is compressed when tension is generated, and thereby eliminating any difference in the tension even if a spring constant k that is determined during compression is small and the amounts of compression are different.
