摘要

PPROBLEM TO BE SOLVED: To provide a sticker adapted to disable the confirmation of the inherent color change information in an ordinary state but to make the verification of the inherent information possible only by observation through a prescribed verification tool and having a verification function adequately usable as a device particularly for prevention of forgery; to provide an authenticity judgment medium pasted with the sticker having the verification function; to provide a thread body having the verification function; and also to provide an authenticity judgment paper sheet internally incorporated with the thread body having the verification function. PSOLUTION: The sticker having the verification function is formed by disposing a metal reflection layer on at least a part of the region on the back side of a birefringent transparent layer and laminating a pasting layer for pasting on a desired medium thereon.
