The X-ray mask manufactured according to the present invention can solve a problem that the thin film stress of the X-ray absorber cannot be made to be zero although the mean thin film stress throughout the X-ray absorber can be made to be zero. The thin film stress distribution over the X-ray absorber 4 after the X-ray absorber 4 has been formed on a silicon substrate 1 is measured, and then inputs of electric power to heaters 9a, 9b and 9c of a hot plate 8 are changed so as to heat the X-ray absorber 4 to temperatures according to a specified temperature distribution with which the thin film stress throughout the X-ray absorber can be made to be zero.
