ABSTRACT:
An X-ray multilayer film reflecting mirror comprises a plurality of substance layers formed on a substrate to be applied to X-rays having a wavelength of 100 .ANG. or less so that a deviation .DELTA. of the film thickness of each layer from a standard value is within a range defined by ##EQU1## where .theta. is the grazing angle of an X-ray being incident and .lambda. is the wavelength of the X-ray. Thus, the multilayer film reflecting mirror having the reflectance which is advantageous in practical use can be stably provided, and a product yield is improved.
