Abstract: An object is to provide a methane synthesis device having as a whole a reduced size and a simplified configuration. A methane synthesis device 100 is composed of respective components from an end plate 2 at the leftmost side to an end plate 23 at the rightmost side and is compactly assembled by fastening plural bolts and nuts to bring these individual components into tightly contact with each other. The components may be divided into a Sabatier reaction unit of signs 3 to 9, a water electrolysis unit of signs 13 to 19, and other components. Hydrogen gas generated in the water electrolysis unit is mixed with carbon dioxide gas and supplied to the Sabatier reaction unit, and methane is synthesized in the Sabatier reaction unit. The size of the device is reduced as a whole and configuration is simplified by integrally stacking the water electrolysis unit, the Sabatier reaction unit, a carbon dioxide supplying unit, and a hydrogen gas supplying unit.
