ABSTRACT:
The present invention serves to provide a stereoscopic sheet structure in which a three-dimensional design appears to be changing by changing the angle of observation. The stereoscopic sheet structure has a convex lens assembly which is formed on one surface of a sheet member and in which a plurality of convex lenses are arranged; and a repeating design portion in which a plurality of design units are arranged on a focal plane of the convex lenses at arrangement intervals and/or in arrangement directions different from those of the convex lenses, and which has a continuously deformed design portion in which the arrangement intervals and arrangement directions of the design units regularly change.
