Disclosed is a carbon dioxide reforming catalyst which enables to react a hydrocarbon supply gas with carbon dioxide while preventing the precipitation of carbon to thereby produce hydrogen and carbon monoxide with high efficiency. Also disclosed is a method for producing the carbon dioxide reforming catalyst. The carbon dioxide reforming catalyst comprises a mixture of a carbonate salt of at least one alkali earth metal selected from the group consisting of Ca, Sr and Ba and a metal catalyst capable of accelerating the decomposition of the hydrocarbon supply gas as the main component. The metal catalyst may be at least one member selected from the group consisting of Ni, Rh, Ru, Ir, Pd, Pt, Re, Co, Fe and Mo. The carbon dioxide reforming catalyst may further comprise ATiO3 [wherein A represents at least one alkali earth metal selected from the group consisting of Ca, Sr and Ba]. The carbon dioxide reforming catalyst can be produced through a process for absorbing carbon dioxide onto an alkali earth-Ti composite oxide having a carbon dioxide-absorbing ability.
