Abstract
In an x-ray absorber in accordance with the present invention, reduced transmittance of the x-ray absorber is suppressed while phase shift amount in the vicinity of π-radians is achieved. For this purpose, a material is used that has a high transmittance per film thickness and contains an element with a high phase shift amount and an element with a low transmittance, as a material composition that forms the x-ray absorber. In other words, the transmittance of the x-ray absorber is mainly determined by the element with a low transmittance, and phase shift falling short of π-radians is compensated with the element with a high transmittance and a high phase shift.
