A X-ray waveguide includes a core for guiding X-rays having a wavelength band in which the real part of refractive index of material is smaller than 1 and a cladding for confining the X-rays in the core. The core has a one-dimensional periodic structure in which a plurality of layers respectively formed of inorganic materials having different real parts of refractive index are periodically laminated. The core and the cladding are configured so that a critical angle for total reflection for the X-rays at an interface between the core and the cladding is larger than a Bragg angle due to a periodicity of the one-dimensional periodic structure. A critical angle for total reflection for the X-rays at an interface between layers in the one-dimensional periodic structure is smaller than the Bragg angle due to the periodicity of the one-dimensional periodic structure.

An X-ray waveguide includes a cladding and a core. The core has a periodic structure formed in at least one period direction. The periodic structure includes periodically arranged members made of material having different refractive index real parts. The core is surrounded by the cladding in the plane perpendicular to a wave-guiding direction. The Bragg angle obtained from the periodicity of the periodic structure is smaller than the total reflection critical angle at which X-rays are incident on the interface between the cladding and the core. The at least one period direction is the direction of at least one fundamental vector expressing the periodicity of the periodic structure in a plane of the core perpendicular to the wave-guiding direction.
