摘要： A method for manufacturing a metal carrier usable for an exhaust gas purifying catalyst, by spirally winding a blank material into the form of metal carrier. In the method according to the invention, two to four sheets of flat metal foils are provided, having projections and holes over entire surfaces thereof, as the metal carrier blank material. The flat metal foils are spirally wound under a mutually overlapped state, into a form of cylindrical body, and the tip ends of the projections are joined to corresponding surfaces of the flat metal foils.
