Observation samples 16 in a sample solution 15 are held due to absorption or the like on the rear face of a first X-ray transmission film 14a. In a mirror body, while an X-ray emission film 13 and X-ray transmission films 14a and 14b are bent to be convex outward due to the pressure difference, an X-ray transmission film 14c is bent to be convex toward the X-ray transmission film 14a side due to gas expansion in a second cavity part 11b. This bending results in widening of a gap between the first and second X-ray transmission films 14a and 14b in the center part of these more compared with a gap between the end parts of these. However, despite the fact that lengthening of the X-ray optical path length over the primary visual field region of X-ray microscope observation arises between the X-ray transmission films 14b and 14c, there is almost no change between the X-ray transmission films 14a and 14c. Accordingly, even when the X-ray emission film and the X-ray transmission films are bent inside the mirror body, lengthening of the X-ray optical path length takes place in the second cavity part 11 b (gas portion) in which X-ray absorption does not take place, this enabling absorption of the X-rays by the sample solution 15 to be suppressed. |
