PROBLEM TO BE SOLVED: To obtain a heat exchanger, in which formation of water film due to condensate at the wake end in the draft direction of a fin is prevented. SOLUTION: A recess 32 and a protrusion 33 are formed at appropriate intervals at the wake end in the draft direction of the fin 3. Thus, formation of the water film becomes difficult, and increase in the draft resistance is suppressed.
