PROBLEM TO BE SOLVED: To reliably mount other parts by securing the effective screw length of a bolt without causing a screw section to be buried with a brazing filler metal in integrated brazing in a flange for heat exchangers. SOLUTION: In the flange 12 for heat exchangers in which at least one screw section 13 penetrating in the thickness direction of a flange body is formed, a counter sink section 15 is formed at the brazed surface side of the screw section 13, thus fixing the brazing filler metal that is melted in integrated brazing at the counter sink section 15 and preventing the brazing filler metal from flowing into the screw section 13.
