摘要：
The purpose of the invention is to obtain an anti-counterfeiting marker sheet that is inexpensive and with which authenticity can be assessed easily. The invention uses an anti-counterfeiting marker sheet (1) characterized in being provided with a substrate (3), and multiple markers (5), which are formed directly on the substrate (3) and the contour shape of which can be recognized by magnified examination. It is preferable that: the markers are not unevenly distributed but are irregularly disposed on the substrate; there are multiple marker (5) colors; and there are multiple types of shapes for the marker (5) contour shapes. It is also preferable that the minimum radius of curvature of the corners of the shapes formed when the markers (5) are viewed in plan view is 250 nm to less than 10µm.
