PROBLEM TO BE SOLVED: To provide an air heat exchanger comprising flat heat transfer tubes and corrugated fins, capable of improving water draining performance of corrugated fin parts in being used as an evaporator. SOLUTION: In this air heat exchanger provided with the plurality of flat heat transfer tubes 2, 2 disposed between headers 3A, 3B, and the corrugated fins 4, 4 disposed among the plurality of heat transfer tubes 2, 2, a width of the corrugated fins 4, 4 are relatively larger than a width of the flat heat transfer tubes 2, 2, and a discharge passage for condensate water is formed by connecting adjacent edge portions 4b, 4b to each other without through the flat heat transfer tubes 2, 2 at an outer side with respect to parts corresponding to the flat heat transfer tubes 2, 2 by cutting the parts corresponding to the flat heat transfer tubes 2, 2, of the corrugated fins 4, 4.
