The invention relates to an artificial intervertebral disc for implantation between two vertebral bodies (W) comprising two end plates ( ) and an elastically deformable disc ( ) pre-stressed between the end plates ( ) in the axial direction, with the disc ( ) lying within a tubular, elastically deformable, fibre ring ( ) and the end plates ( ) being in tensile communication with the fibre ring ( ). The disc ( ) has a contact surface ( ) which enlarges with a compression of the artificial intervertebral disc and which adjoins one of the end plates ( ) so that the elastic properties of the artificial intervertebral disc show a non-linear behaviour with increasing deformation at least with respect to a compression force (F).
