PROBLEM TO BE SOLVED: To provide a flux application device capable of automatically and uniformly applying a viscous liquid-like flux to a corrugated top part of a corrugated parts. SOLUTION: A viscous liquid-like flux 9 is uniformly applied to a corrugated top in a process where a pair of flux application endless belts 1, 2 are uniformly and elastically brought into contact with the corrugated top part of an outer fin 6 by a backing plate 5 with a specified contact pressure by introducing the outer fin 6 between the flux application endless belts 1, 2, and the outer fin 6 is fed in one direction.
