PROBLEM TO BE SOLVED: To provide a heat exchanger capable of preventing degradation of heat exchanging performance in the heat exchanger. SOLUTION: This heat exchanger 20 is composed of a plurality of blocks 20a, 20b, 20c, and comprises a heat transfer fin 4 and a plurality of heat transfer tubes 51. The heat transfer fin is disposed in the air current. The plurality of heat transfer tubes are inserted to the heat transfer fin, and disposed in the direction roughly orthogonal to the flowing direction of the air current. The heat transfer fin has bent parts 61, 62. The plurality of blocks are divided at the bent parts as boundaries. The plurality of heat transfer tubes have liquid tube connecting parts 71a, 72a, 73a and gas tube connecting parts 71b, 72b, 73b. The liquid tube connecting parts are connected to a liquid tube 23. The gas tube connecting parts are connected to a gas tube 24. The liquid tube connecting parts and the gas tube connecting parts are disposed in the different blocks of the plurality of blocks.
