STRUCTURE THREE-DIMENSIONAL CODE AND ANTI-COUNTERFEITING METHOD
FIG5b is a stereoscopic view of the region shown in FIG5a  FIG3b is a stereoscopic view of the region shown in FIG3a
FIG5b shows a stereoscopic view corresponding to the partial region shown in FIG5a. From FIG5b, it may be seen that a bar code pattern formed by the coding pattern 22 on the anti-counterfeiting feature layer 21 is concave.  FIG3b shows a stereoscopic view corresponding to the partial region shown in FIG3a. From FIG3b, it may be seen that a bar code pattern formed by the coding pattern 22 on the anti-counterfeiting feature layer 21 is convex.
