Claim 0:
1. An imaging type X-ray microscope comprising:
an X-ray irradiation unit having a microfocal and high-power X-ray source and a condenser mirror for focusing and irradiating the emitted X-rays toward a sample,
a sample holding unit for holding the sample,
a reflecting mirror type X-ray lens unit for imaging X-rays transmitted through the sample, and
an imaging unit for acquiring the imaged X-ray image, wherein
each mirror constituting the condenser mirror and the reflecting mirror type X-ray lens unit has a reflecting surface formed with a multilayer film having a high reflectivity in X-rays of a specific wavelength,
the reflecting mirror type X-ray lens unit is a Wolter type mirror set capable of reflecting in a first direction perpendicular to the X-ray irradiation direction and a second direction perpendicular to the first direction, and
the multilayer film is formed by alternately and periodically stacking layers formed of a heavy element and layers formed of a light element are alternately stacked and with an error of 0.5 Å or less with respect to the designed periodicity.
