As shown in FIG. 1 and FIG. 2, in the heat exchanger 30 of the air conditioner according to the present invention, a plurality of fins 31 and tubes which penetrate the fins 31 and are arranged at a predetermined interval. The heat exchanger 30 is constituted by 33. The installation intervals (step pitches) of the tubes 33 to be piped are set to be gradually different according to the installation position of the cross-flow fan 35 installed on the side of the heat exchanger 30. That is, the installation interval (step pitch = dl) of the tubes 33 of the heat exchanger 30 that are located close to the cross-flow fan 35 is set to be short with respect to the position of the cross-flow fan 35, and the farther away from the cross-flow fan 35, the more heat is generated. Installation interval of the tubes 33 of the exchanger 30 (step pitch = d
