PROBLEM TO BE SOLVED: To realize a compact and lightweight hydrogen production device capable of generating hydrogen with high efficiency using carbon. SOLUTION: Steam 1 fed from a steam feed port and activated carbon fed from an activated carbon feed port 2 are held to the upper part of a porous plate 8 installed in the lower part of a reaction tube 9. A microwave 4 generated at a microwave generator passes through a waveguide 5 and is irradiated to the reaction tube 9. The microwave raises the temperature of the activated carbon 7 to about 1,000°C by self-heating. Under the condition of temperature 1,000°C, carbon and steam are reacted as shown in C+H<SB>2</SB>O→CO+H<SB>2</SB>, so as to generate hydrogen and carbon monoxide. The hydrogen and carbon monoxide generated by the above reaction pass through the porous plate 8, and are recovered as gaseous hydrogen and carbon monoxide 16 at the outside of the reaction tube 9.
