PURPOSE:To prevent a gas side flow passage and an air side flow passage from being filled with an excessive flow of a brazing filler metal, and also, to manufacture the brazing filler metal at a low cost, at the time of joining air-tightly both and faces of a corrugated plate formed like a wave plate to a partition flange. CONSTITUTION:A brazing filler metal 52 obtained by mixing at least one of stainless steel 30 and nickel particles in a ratio of 0.5-2 weight against 1 weight of a powdery nickel brazing filler metal 31 is cast into the periphery of a corrugated plate 1 erected in a partition flange 10 and laminated, the laminated brazing filler metal is heated to a brazing work temperature of the powdery nickel brazing filler metal 31, and the partition flange and the corrugated plate are fused by the brazing filler metal which becomes like a sintered metal.
