PROBLEM TO BE SOLVED: To provide an X-ray optical device with a simple structure, capable of efficiently collimating and emitting a generated X-ray.SOLUTION: An X-ray optical device includes an X-ray reflecting structure 3 consisting of at least three X-ray reflecting substrates 11 arranged at an interval, where each X-ray entered into a plurality of X-ray passages having both sides sandwiched by the X-ray reflecting substrates 11 is reflected and collimated at the X-ray reflecting substrates 11 on both sides of each X-ray passage and is emitted from each X-ray passage. When one end surface of the X-ray reflecting structure 3 is an inlet of the X rays and the other end surface is an outlet of the X rays, a pitch between the X ray reflecting substrates 11 at the outlet is wider than that thereof at the inlet. |
