PROBLEM TO BE SOLVED: To provide a hydrogen production method which can convert an organic substance into hydrogen by efficiently reforming the organic substance by using a gas capable of being stably supplied, and can stably produce hydrogen at high efficiency with minimal production amounts of heavy fractions or carbonaceous materials, and furthermore which can be implemented by using relatively simple equipment, in a method for producing hydrogen by reforming an organic substance.SOLUTION: In producing hydrogen by reforming an organic substance, excess water vapor is added to an exhaust gas (g) containing carbon monoxide generated by a metallurgical furnace and a shift reaction is carried out, thereby constituting a mixed gas (g) containing hydrogen and carbon dioxide produced by the shift reaction, and water vapor not consumed by the shift reaction. The mixed gas (g) is brought into contact with the organic substance, bringing about a reforming reaction which converts the organic substance into lower molecules, and the product generated by the reforming reaction is steam reformed, thereby producing hydrogen.
