PROBLEM TO BE SOLVED: To facilitate curving work of a stacked air heat exchanger. SOLUTION: The air heat exchanger comprises pipe-like upper and lower headers 12A and 12B for receiving and delivering refrigerant, a plurality of flat heat exchanger tubes 1, 1, and so on juxtaposed between the upper and lower headers 12A and 12B at prescribed intervals in the longitudinal direction, while communicating with the upper and lower headers 12A and 12B, and corrugated fins 11, 11, and so on arranged vertically between the plurality of flat heat exchanger tubes 1, 1, and so on where bending deformation is facilitated by dividing the corrugated fins 11, 11, and so on into a plurality of sheets of corrugated fins 11A, 11A,..., 11B, 11B and so on in the inner and outer circumferential direction.
