Abstract
An X-ray waveguide according to the present invention includes: a core for guiding an X-ray in such a wavelength band that a real part of the refractive index of a material is 1 or less; and a cladding for confining the X-ray in the core, wherein: the cladding has a periodic structure in which multiple materials having different real parts of the refractive index are periodically arranged in two-dimensional directions perpendicular to the guiding direction of X-ray; and the periodic structure has a period of 100 nm or less.
