PROBLEM TO BE SOLVED: To provide X-ray radiographic equipment radiographing phase contrast of high image quality. SOLUTION: The X-ray radiographic equipment 1 is provided with: an X-ray source 11 for emitting X-rays; a subject table 13; an X-ray detector 16 wherein conversion elements for generating electric signals according to the emitted X-rays are two-dimensionally arranged, and the electric signals generated by the conversion elements are read as image signals; and a first grid 14 and a second grid 15 comprising a plurality of slits. The subject table 13, the first grid 14, the second grid 15, and the X-ray detector 16 are arranged in this order in the emitting direction of the X-rays by an X-ray source 11. The first grid 14 and the second grid 15 are held by the same holding part 17, so that the positional relation between the first grid 14 and the second grid 15 in the emitting direction of the X-rays are fixed.
