The present invention relates to a security element (16) for security papers, value documents and the like, having a microoptical moiré-type magnification arrangement for depicting a moiré image (84) having one or more moiré image elements (86), having

    a motif image that includes a periodic or at least locally periodic arrangement of a plurality of lattice cells (24) having micromotif image portions (28, 28′, 28″),for the moiré-magnified viewing of the motif image, a focusing element grid (22) that is arranged spaced apart from the motif image and that includes a periodic or at least locally periodic arrangement of a plurality of lattice cells having one microfocusing element (22) each,wherein, taken together, the micromotif image portions (28, 28′, 28″) of multiple spaced-apart lattice cells (24) of the motif image each form one micromotif element (50) that corresponds to one of the moiré image elements (86) of the magnified moiré image (84) and whose dimension is larger than one lattice cell (24) of the motif image.
