PROBLEM TO BE SOLVED: To provide a hydrogen separation device whose durability is improved by suppressing the generation of a hole in a palladium-based separation membrane. SOLUTION: On the basis of the knowledge that metal particles generated by reducing metal oxide particles stuck to the surface of the palladium-based separation membrane strongly react with the palladium-based separation membrane and are diffused from each other and thus holes are generated, the hydrogen separation device includes a hydrogen separation membrane which sections a primary side space and a secondary side space and includes palladium or a palladium alloy, a gas-to-be-separated supply means for supplying a gas to be separated, which contains hydrogen, to the primary side space, and an oxygen supply means for causing oxygen to be contained in the gas to be separated inside the primary side space when separating the hydrogen from the gas to be separated by the hydrogen separation membrane.
