The invention relates to a leaf spring (1) for motor vehicles, which is made of a fiber-reinforced synthetic material and can absorb potentially occurring lateral forces and transfer them to a leaf spring receiving device, comprises a first end (2) and a second end (3), which can each be fixed in a leaf spring receiving device in a torsion-proof and non-displaceable manner, and a bending joint section (11), which can compensate for a change in length of a resilient section (8) of the leaf spring (1) during a load-induced deformation of the resilient section (8). The leaf spring (1) comprises a first spring limb (5) and a second spring limb (6) which are connected to each other via a transition section (7). In a non-loaded state, both the first spring limb (5) and the second spring limb (6) are approximately planar and disposed at an angle relative to each other. The first spring limb (5) forms the resilient section (8). The bending joint section (11) contains the second spring limb (6). The second spring limb (6) is shorter than the first spring limb (5) and oriented approximately perpendicularly to the first spring limb (5). The leaf spring (1) is integrally produced from unidirectional prepregs having a duroplastic or thermoplastic matrix by means of a pressing method.
