摘要： [Problem] To protect the gas-inlet-side edge surfaces of a catalyst support having an offset structure from wind erosion.
[Solution] A base for supporting a catalyst for exhaust gas purification, the base including a honeycomb structure obtained by superposing a metallic flat foil and a metallic wavy foil, characterized in that the wavy foil has offset portions where any adjoining two of the wave phases arranged in the axial direction of the honeycomb structure are offset from each other. The base is further characterized in that an oxide coating film has been formed in a given range of these offset portions which includes exposed edge surfaces that are exposed on the gas-inlet side, that the oxide coating film includes 30-99.9 mass% first alumina, with the remainder comprising at least one of second aluminas, Fe oxides, and Cr oxides, that the first alumina comprises α-alumina, that the second aluminas comprise one or more of γ-, θ-, χ-, δ-, η-, and κ-aluminas, and that the given range extends from the exposed edge surfaces to a distance of at least 2 mm therefrom along the gas flow direction.
