Abstract: A fin for a heat exchanger is joined to an outer surface of a tube, and facilitates a heat exchange between the tube and an air flowing around the tube. A sectional surface of the fin perpendicular to a flowing direction of an air has a corrugated shape that includes multiple flat portions substantially parallel to a flowing direction of the air, and a ridge portion connecting the adjacent flat portions. Multiple louvers cut in and raised from each of the flat portions at a predetermined cut-and-raised angle are disposed on the flat portion along a flowing direction of the air. A thickness of each flat portion is defined as t, a louver pitch of the louvers is defined as PL, and the thickness of each flat portion and the louver pitch satisfy a relationship of 0.035≦t/PL≦0.29.
