摘要
A heat exchanger includes a plurality of plate-shaped fins disposed at intervals, and a plurality of heat transfer tubes disposed to be inserted into through holes of the fins in a direction perpendicular to the fins. In each of the fins, a starting hole is formed between adjacent through holes, and the starting hole serves as a start point of bending of the fins and has a vertex portion at a bending portion of each fin which is close to an edge thereof. In each of the fins, a cut is made to connect the other edge of the fin and a side of the starting hole which is located opposite to the vertex portion of the starting hole. The above each fin is bent at the vertex portion of the starting hole, by opening the cut from the starting hole.
