Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hydrogen separation membrane in which a middle layer for preventing the mutual diffusion between a base metallic layer and a coated metallic layer, and the oxidation of alloy components of the base metallic layer is formed at low cost, a manufacturing method therefor, and a hydrogen manufacturing apparatus provided therewith.SOLUTION: The hydrogen separation membrane 11 includes the base metallic layer 12 composed of a group 5A metal or its alloy, the middle layer 13 formed on the surface of the base metallic layer 12 and the coated metallic layer 14 formed on the middle layer 13; and the middle layer 13 is formed by anodic oxidation of the base metallic layer 12. The manufacturing method for the hydrogen separation membrane 11 has a step of forming the middle layer 13 by anodic oxidation of the base metallic layer 12 and a step of forming the coated metallic layer 14 on the middle layer 13, and the hydrogen manufacturing apparatus has the hydrogen separation membrane 11.
