The heat exchanger comprises a finned zigzag tube 1 comprising a zigzag tube member 2 formed by bending a pipe having no welded seams, the zigzag tube member 2 having at least three straight tube portions 2a arranged from the front rearward at a spacing and parallel to one another, a plurality of first fin groups 3 arranged at a spacing on two adjacent straight tube portions 2a of the zigzag tube member 2 longitudinally of the straight tube portions and each comprising plate fins 5 extending across and fixedly arranged in parallel on the adjacent straight tube portions 2a, and a plurality of second fin groups 4 each comprising plate fins 6 fixedly arranged in parallel on each remaining straight tube portion 2a of the zigzag tube member 2, the second fin groups 4 being arranged at a spacing on the remaining straight tube portion 2a longitudinally thereof so as to be in the same positions as the respective first fin groups 3 with respect to the longitudinally direction of the straight tube portions 2a. The heat exchanger E comprising the finned zigzag tube 1 exhibits the desired refrigeration performance with the leakage of refrigerant diminished.
