PROBLEM TO BE SOLVED: To provide a new catalytic structure containing a metal oxide having effective catalytic activity as a catalyst and a method for manufacturing the new catalytic structure containing the metal oxide. SOLUTION: The new catalytic structure is manufactured by depositing a hydroxide and/or an oxide of a metal selected from group IV to group VIII in the periodic table in the surface layer part of an inactive carrier and firing the carrier thus deposited at 200-800°C. The catalytic structure is characterized in that the metal oxide having catalytic activity exists in the surface layer part of the catalytic structure, particularly, in the surface layer part of 1-1,000μm depth from the outermost surface of the catalytic structure but does not exist substantially in the internal layer except the surface layer part.
