A leaf spring, in particular for automotive suspensions, wherein a central core, e.g. of varying thickness, made of a polymer material having predetermined mechanical characteristics and no reinforcing fibers, is covered on two opposite work surfaces with respective laminates, e.g. of constant thickness, made of composite material. The central core has a longitudinal axis substantially coincident with a neutral axis of the leaf spring; and a predetermined number of transverse holes, by which to fasten the leaf spring to respective mechanical members, are formed through the central core, at the longitudinal axis, without affecting the laminates of composite material.
