PROBLEM TO BE SOLVED: To provide a heat exchanger wherein no interference is caused mutually stacking state, and workability and productivity are improved even in a thinned heat exchanger. SOLUTION: This heat exchanger has: a plurality of heat radiating fins 11 juxtaposed at a prescribed interval, and allowing heat exchange air to flow to mutual clearance; a heat exchange pipe 12 penetrating through these heat radiating fins, and forming a passage for conducting a heat exchange medium inside; and a distributing branch pipe 14 connected to this heat exchange pipe, and introducing, guiding, and separating the heat exchange medium to the heat exchange pipe or merging, deriving, and guiding the heat exchange medium. The distributing branch pipe has a U-shaped pipe part 15 forming an almost U shape, and connected to the mutual opening ends of a pair of heat exchange pipes, and a pipe connecting part 16 projected in this U-shaped pipe part by forming a rising angleθlarger than 90°, and smaller than 180°in the shaft direction of the U-shaped pipe part.
