Security element for manufacturing documents of values, as banknotes, checks or the like, the security element comprising: - a dielectrical substrate, - a line grid, comprising first grid bars which extend along a longitudinal direction and are located in a first plane and which are embedded in the substrate, and second grid bars, which extend along the longitudinal direction and are located in a second plane being parallel to the first plane and which are embedded in the substrate, wherein -- the first and the second grid bars (3, 7) each consist of a highly refractive material, -- the second grid bars are, in relation to the first plane, located fully above the first grid bars such that the first and the second grid bars (3, 7) do not form a continuous film, and -- the first grid bars each have a width and are spaced at a distance adjacent to each other such that first grid gaps extending along the longitudinal direction and having a width corresponding to the spacing are formed between the first grid bars, -- the arrangement of the second grid bars is inverted to that of the first grid bars, such that in top view onto the first or the second plane the second grid bars are located above the first grid gaps and that second grid gaps which exist between the second grid bars are located below the first grid bars, -- the width of the first grid bars and the second grid gaps, the width of the second grid bars and the first grid gaps, and a thickness of the first grid bars and of the second grid bars are each below 300 nm, -- several regions are formed in the security element, which regions are different regarding a structure of the line grid, wherein the different regions code at least one motive which can be seen in a top view of the security element, characterized in that - in top view a metallized relief structure is positioned below the line grid, which relief structure comprises different areas being different from each other regarding the relief and the reflection of radiation, wherein the different aras of the metallized relief structure are assigned to the different regions of the line grid and structure the motive further. -
