PROBLEM TO BE SOLVED : To provide a metallic honeycomb base material for an exhaust gas cleaning catalytic converter having excellent oxidation resistance at high temperature, the durability of which can be improved at higher temperature even when a rare earth metal component, an alkaline-earth metal component, a group 4A metal component or a group 5A metal component is added to a catalyst layer and to provide the catalytic converter for cleaning exhaust gas. SOLUTION : The honeycomb base material for the exhaust gas cleaning catalytic converter having excellent oxidation resistance at high temperature is a metallic honeycomb base material obtained by fabricating stainless steel foil on the surface of which a film of a precursor is formed. This metallic honeycomb base material is used in the catalytic converter for cleaning exhaust gas. COPYRIGHT : (C)2006, JPO&NCIPI
