Disclosed is an X-ray reflecting device and an X-ray reflecting element constituting the X-ray reflecting device capable of facilitating a reduction in weight and being prepared in a relatively simple manner. The X-ray reflecting element of the present invention comprises a body made of a solid silicon, and a plurality of slits formed in the body in such a manner as to penetrate from a front surface to a back surface of the body. Each of the slits has a wall surface serving as an X-ray reflecting surface. To allow the slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other, the X-ray reflecting device of the present invention comprises a plural number of the X-ray reflecting elements, which are formed into a multilayered structure in such a manner or arranged side-by-side in a horizontal direction in such a manner as to allow the slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other, or stacked on each other in a vertical direction to form a stacked structure in such a manner as to allow the slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other. Further, the X-ray reflecting device may comprise a plural number of the stacked structures arranged side-by-side in a horizontal direction.
