Zusammenfassung:An inner rib, in particular for a flat tube, in particular of a heat exchanger, made from a metallic flat strip, which is shaped in a wavy modulated manner, having a large number of wave crests and wave troughs, which are each arranged alternately in a longitudinal direction of the inner fin, an essentially straight, web-like fin area being provided between one wave crest and an adjacent wave trough and connecting the wave crest to the wave trough, the metallic flat strip having a first strip thickness L1, which is essentially constant in the area of the wave crests and the wave troughs, the flat metallic strip having a second strip thickness L2, which is provided in the area of the web-like fin area, L2 being smaller than L1.
