A fin for a heat exchanger is provided that includes a fin element which extends in a flow direction of a first fluid and has a wall face around which the first fluid flows on both sides, wherein at least one flap is provided in the wall face, which flap forms a cutout, through which the first fluid can flow, in the wall face, wherein a first straight edge of the flap extends substantially perpendicularly to the flow direction and is arranged at a distance from the wall face in order to form the cutout, wherein the flap has an inclined, smooth tab face which terminates at the first straight edge, and wherein the tab face is connected to the wall face via two side walls of the tab, which side walls have a curved profile mirror-symmetrically with respect to each other and, starting from the first edge, have a height which decreases in a manner corresponding to the inclination of the tab face.
