1. A soller slit comprising a plurality of metal foils and a plurality of spacers, the plurality of said spacers being laminated alternatively with the plurality of said metal foils to support one end portions of said metal foils with a space between adjacent metal foils.  the other end portions of said metal foils being opened.  said soller slit includes a plurality of metal foils and a plurality of spacers, the plurality of said spacers being laminated alternatively with the plurality of said metal foils to support one end portions of said metal foils with a space between adjacent metal foils, the other end portions of said metal foils being opened, and wherein  said the other end portions of said metal foils are arranged in contact with or in the vicinity of a surface of said specimen.  said soller slit includes a plurality of metal foils and a plurality of spacers, the plurality of said spacers being laminated alternatively with the plurality of said metal foils to support one end portions of said metal foils with a space between adjacent metal foils, the other end portions of said metal foils being opened, and wherein  said the other end portions of said metal foils are arranged in contact with or in the vicinity of a surface of said monochromator. 2. A soller slit as claimed in claim 1, wherein each said spacer has a center portion protruding forward and both side portions being behind. 3. A soller slit as claimed in claim 2, wherein said center portion of said spacer takes in the form of an apex of a mountain. 4. An X-ray apparatus comprising an X-ray source for generating X-rays, an X-ray detector for detecting X-rays diffracted by a specimen after being generated from said X-ray source, and a soller slit, wherein 5. An X-ray apparatus comprising an X-ray source for generating X-rays, an X-ray detector for detecting X-rays diffracted by a specimen after being generated from said X-ray source, a monochromator for making X-rays generated by said X-ray source or X-rays diffracted by said specimen monochromatic, and a soller slit, wherein
