1. An X-ray reflecting device comprising a plurality of X-ray reflecting elements, each of said X-ray reflecting elements comprising:a body composed of a silicon plate; anda plurality of slits formed in said body through an etching process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface,wherein said plurality of X-ray reflecting elements are stacked on each other in a vertical direction and arranged side-by-side in a horizontal direction in such a manner as to allow said slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other. 2. An X-ray reflecting device comprising a plurality of X-ray reflecting elements, each of said X-ray reflecting elements comprising:a body composed of a silicon plate; anda plurality of slits formed in said body through an etching process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface,wherein said plurality of X-ray reflecting elements are arranged side-by-side along a hypothetical spherical surface in such a manner as to allow said slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other. 3. An X-ray reflecting device comprising a plurality of stacked structures each formed by stacking a plural number of X-ray reflecting elements on each other in a vertical direction in such a manner as to allow slits in the X-ray reflecting elements to be located in a given positional relationship with each other, said plurality of stacked structures being arranged side-by-side along a hypothetical spherical surface, wherein each of said X-ray reflecting elements comprises:a body composed of a silicon plate; anda plurality of said slits formed in said body through an etching process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface. 4. An X-ray reflecting element comprising:a body composed of a metal plate; anda plurality of slits formed in said body through an X-ray LIGA process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface, wherein said X-ray reflecting surface has a surface roughness of 100 angstroms or less. 5. An X-ray reflecting element comprising:a body composed of a metal plate; anda plurality of slits formed in said body through an X-ray LIGA process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface, wherein said body includes fastening means for allowing a plural number of said X-ray reflecting elements to be fastened to each other. 6. An X-ray reflecting device comprising a plurality of X-ray reflecting elements, each of said X-ray reflecting elements comprising:a body composed of a metal plate; anda plurality of slits formed in said body through an X-ray LIGA process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface,wherein said plurality of X-ray reflecting elements are stacked on each other in a vertical direction and arranged side-by-side in a horizontal direction in such a manner as to allow said slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other. 7. An X-ray reflecting device comprising a plurality of X-ray reflecting elements, each of said X-ray reflecting elements comprising:a body composed of a metal plate; anda plurality of slits formed in said body through an X-ray LIGA process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface,wherein said plurality of X-ray reflecting elements are arranged side-by-side along a hypothetical spherical surface in such a manner as to allow said slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other. 8. An X-ray reflecting device comprising a plurality of stacked structures each formed by stacking a plural number of X-ray reflecting elements on each other in a vertical direction in such a manner as to allow slits in the respective X-ray reflecting elements to be located in a given positional relationship with each other, said plurality of stacked structures being arranged side-by-side along a hypothetical spherical surface, wherein each of said X-ray reflecting elements comprises:a body composed of a metal plate; anda plurality of slits formed in said body through an X-ray LIGA process in such a manner as to penetrate from a front surface to a back surface of said body, each of said slits having a wall surface serving as an X-ray reflecting surface.
