Abstract
An X-ray shield grating includes a substrate on which a plurality of recessed portions are arranged, and metal that is arranged in each of the recessed portions. The substrate includes a bent region that is bent in an arrangement direction in which the plurality of recessed portions are arranged. A radius of curvature of the bent region is 200 millimeters or less. In the bent region, a maximum value of a width of a region sandwiched between two adjacent recessed portions of the plurality of recessed portions and a width of the substrate in an end portion of the bent region are less than or equal to three times a minimum value of the width of the region sandwiched between the two adjacent recessed portions.
