Zusammenfassung:PROBLEM TO BE SOLVED: To simultaneously perform a work for integrally forming the pipe end parts of a plurality of the branch pipes made of stainless steel pipe of an exhaust manifold and a work for assembling the integrally formed pipe end parts to an assembly member. SOLUTION: The pipe end parts 5 and 6 of branch pipes made of a stainless steel pipe are inserted in an assembly member 12 made of a casting to interconnect a branch pipe and the assembly member 12. Simultaneously, a sheet-form brazing material 8 is located between mating surfaces 3 and 4, positioned facing each other, of the pipe end parts 5 and 6, and the pipe end parts 5 and 6 of branch pipes adjoining each other are interconnected by brazing.
