PROBLEM TO BE SOLVED: To provide a palladium-based hydrogen separation membrane which has excellent hydrogen selective permeability and high permeation rate in a temperature region ranging from low temperature to high temperature, and is durable indicating stable performance without causing hydrogen brittleness and membrane breakdown. SOLUTION: This hydrogen separation material is made up of a mixed sintered material layer of a stabilized zirconia particle and an alumina particle borne by a porous base, and a palladium metal or palladium alloy layer packed in the gap between the particles of the mixed sintered material layer. That is, a binder is added to the mixture of a stabilized zirconia sol and an alumina sol, and thereby, the mixture sol is prepared. After that, the mixture sol is applied to the surface of the porous base, and calcined at 500 to 800°C to obtain the formed mixed sintered material layer. Next, a nuclide is dispersed in at least part of the mixed sintered material layer and the palladium metal or the palladium alloy are packed in the gap between the particles of the sintered material layer by electroless plating process.
