PROBLEM TO BE SOLVED: To irradiate a microregion on a sample with X rays of a high intensity by improving the focus blur at a focusing end of a multi-capillary X-ray lens. SOLUTION: A drawing member 3 whose inner surface shaped like a truncated cone is mirror-finished is set up outside the focusing end 2a on the exit side of the multi-capillary X-ray lens (MCX) 2, the X rays emitted from an X-ray source by the MCX 2 are efficiently collected, the diameter of the X rays is reduced to some extent, the X rays are introduced into the drawing member 3 and the convergence diameter of the X rays is reduced further while giving the total reflection of the X rays on the inner surface of the drawing member 3; so that the X rays can be focused on a small region 4.
