To improve heat responsibility by coating a catalyst comprising at least one kind selected from Ti, Al, Si, Zr, Ni, Fe, Co, Cu, Zn, Pt, Pd, Ru, and Rh on a metal honeycomb carrier.
A metal thin plate 21 is fed from a roll 20 and introduced into a vacuum atmosphere through a pressure difference roll 23, and the surface is cleaned by sputtering with Au ions released from a high frequency sputtering electrode 24. Next, the thin plate 21 is introduced into an evaporation chamber 27 and led to an oxidation furnace after the vapor deposition of Al vapor evaporated from an evaporation crucible 26, and an oxidized coat and whiskers are formed to make a honeycomb-shaped carrier. On the metal honeycomb carrier, a catalyst comprising at least one kind selected from Ti, Al, Si, Zr, Ni, Fe, Co, Cu, Zn, Pt, Pd, Ru, and Rh is coated. In this way, heat responsibility can be improved.
