Disclosed is a grid configured of a plurality of small grids, wherein intervals between the small grids are reduced. Each of the small grids does not have an outer rim portion, and has a grid portion formed on the entire surface. On the grid portion, a pair of first alignment marks are formed. The first alignment marks are radiolucent, and are disposed close to two sides facing each other. On a supporting substrate, second alignment marks are formed. Each of the small grids is attached to the supporting substrate after having the position adjusted such that each of the first alignment marks and each of the second alignment marks accord with each other.
