PURPOSE: A carbon dioxide reforming catalyst and a method for manufacturing the same are provided to improve carbon resistance property, catalyst stability at high temperatures, and catalytic activity by preventing the inactivation of a catalyst due to the precipitation of carbon. CONSTITUTION: A carbon dioxide reforming catalyst is represented by Pd-Ce-SiO2. In the chemical formula, the content of Pd is 0.2-1.0 weight% based on the total weight of the catalyst; and weight% ratio of Ce/SiO2 is in the range of 0.05-0.5. The catalyst is manufactured by a co-precipitating method which mixes and stirs starting materials of Pd, Ce, and SiO2 and adds an alkaline aqueous solution into the stirred product to obtain a precipitate.
