To provide a method and a device for hydrogen production excellent in reactivity and efficiency.

This device for hydrogen production is provided with a reactor 71 for performing the reaction of generating a hydrogen-containing gas by instantaneously releasing a high pressure gas to generate shock waves and introducing the shock waves into a reaction chamber to perform shock compression of a raw material in the chamber, and an emulsion-feeding apparatus 74 for feeding to the reaction chamber 73, an emulsion prepared by agitating a mixed liquid including a raw material oil and water as the raw material for hydrogen production. Further, the device is provided with an analyzing apparatus 96 for analyzing the hydrogen concentration of the gas generated by the reactor 71, and an adjustment means 97 for adjusting the water addition ratio in the emulsion on the basis of the analytical value from the analyzing apparatus 96.
