A flexible spring element is made of a fibre-reinforced plastics composite material, a functional layer made of a fibre-reinforced plastics composite material being located on each of two mutually opposite sides of a central plane of the flexible spring element. At least one matrix material discharge layer extending parallel to the two functional layers and in a longitudinal direction is arranged in at least one longitudinal portion and has at least a fraction of discharge layer fibres which are oriented differently from the longitudinal direction of the flexible spring element. Within at least one curved portion of the flexible spring element a first volume fraction of flexible spring fibres in the functional layers is smaller, preferably smaller by several % than a second volume fraction of flexible spring fibres in the functional layers within the at least one longitudinal portion.
