A beryllium window comprises a disk-shaped beryllium plate containing beryllium as an essential element, a welding film partially merged into the outer peripheral portion of the beryllium plate and formed of a substance having at least one element selected from the group consisting of silver, gold, nickel and copper, and a reinforcing unit of a stainless steel, and the welding film is partially merged into the reinforcing unit, wherein the welding film fixes the beryllium plate to the reinforcing unit through diffusion welding so that the beryllium window is less deformative against heat stress.
