A honeycomb catalyst capable of stably removing carbon monoxide in a hydrogen-containing gas with high efficiency and a method for producing the catalyst are provided. A honeycomb catalyst for carbon monoxide methanation, wherein a catalyst layer is formed on the surface of a honeycomb substrate made of metal or ceramics, and the catalyst layer is made of a metal and a metal oxide. The metal oxide is one or more oxides selected from ZrO 2 , CeO 2 , NiO, CoO, Co 3 O 4 , Al 2 O 3 , TiO 2 , and SiO 2 , or a composite oxide, and the metal is One or more metals selected from Group 4B, Group 6A, Group 7A and Group 8. The present invention relates to a carbon monoxide methanation honeycomb catalyst in a hydrogen-containing gas, a method for producing the catalyst, and a carbon monoxide methanation method using the catalyst.
