Minute metallic pattern and manufacturing method therefor

摘要

Disclosed herein is an individual minute metallic pattern (1) characterized by having grooves of V-shape cross section on a surface thereof formed by a high hardness cutting tool (15). Such individual minute metallic patterns can be manufactured by etching a thin metal plate supported on the first adhesive sheet to thereby forming a target pattern and a pattern for preventing improper positioning arranged on peripheral portions of the target pattern on the first adhesive sheet;
grooving a surface of said target pattern with a high hardness cutting tool to thereby forming a minute metallic pattern having grooves (4) of V-shape cross section;
adhering a second adhesive sheet on a surface of the minute metallic pattern and the pattern for preventing improper positioning;
exposing a back face of the minute metallic pattern and the pattern for preventing improper positioning by peeling the first adhesive sheet;
forming a fixing layer (5) on the back face of the minute metallic pattern; and
laying a release sheet on the fixing layer.
