PURPOSE:To provide the titled alloy having excellent properties wherein hydrogen permeability is high and the generation of a beta hydride phase is not recognized, by containing Si in a Pd base alloy such as Pd-Ag to make the same amorphous. CONSTITUTION:An alloy consisting of, on an atomic % basis, 9-30% of Si, 20% or less of X (one or more of Ag, Au, Cu, Ni and/or Fe) and the remainder of Pd is processed by an ultra-quenching method to obtain an amorphous Pd-Si-X alloy foil. This alloy foil is high in hydrogen permeability and generates no deterioration in material quality with the formation and disappearance of an alpha-phase/beta-phase hydride phase as absorved in a crystalline Pd-alloy.
