Claim:
A security document, in particular a value-bearing paper, comprising at least one security element provided on a surface of the substrate forming the security document, wherein to form the security element at least one surface region of the security document is of a configuration and size specific to the respective security document in such a way and is spatially displaced, for example recessed or raised, at least relative to the surface of the substrate which is adjacent or surrounding the surface region, and/or is of such a different roughness, hardness, elasticity, slipperiness, thermal conductivity and/or stickiness, that the configuration and size of the surface region can be established as a consequence of the differing surface nature thereof by means of the human sense of touch, and wherein the at least one surface region is formed by a film portion which is of a corresponding configuration and which is applied to the substrate and which comprises a material different from the substrate and which has openings through which the surface of the substrate can be felt.
