<p>It is an object of the present invention to provide a hydrogen production method capable of promoting a water-vapor reforming reaction of ethanol and an absorbing reaction of carbon dioxide by a carbon dioxide absorbent in a well-balanced manner. This hydrogen production method comprises supplying ethanol to a reactor which is filled with a reforming catalyst and a carbon dioxide absorbent containing a lithium composite oxide, and heating the reactor under the condition that the inside thereof is pressurized to 3 to 15 atm to carry out water-vapor reforming of the ethanol.</p>
