When an X-ray focused by using an X-ray lens is irradiated to a sample, there is generated an X-ray halo component at the peripheral part of the focal point of the focused X-ray in the sample and, by this, precision of an analysis of a microscopic region becomes an issue. In order to control the shape of the X-rays from the X-ray lens, a collimator is installed between the X-ray lens and the sample, with an opening part having a tapering shape in which the opening at the side toward the sample is made smaller than that at the side toward the X-ray lens.
