Abstract
A hydrogen permeable structure includes a base material (1) including porous ceramic, and a hydrogen permeable film (2) formed on the base material (1), including palladium (Pd) and at least one element other than palladium and having an amount of hydrogen dissolution at a prescribed temperature smaller than that of palladium alone. The hydrogen permeable film (2) is formed on the surface of the porous ceramic base by a physical vapor deposition technique after any pin holes in the surface of the base have been filled with a porous oxide material.
