摘要

PROBLEM TO BE SOLVED: To provide an authenticity authentication object which allows an authentication structure which is impossible to be forged to be provided in other information recording parts such as a hologram and an IC chip without affecting functions the information recording parts, and which can realize simplification of manufacturing processes and reduction of manufacturing costs.SOLUTION: An authenticity authentication object comprises: an authentication structure for authenticity authentication; and an information recording part in which predetermined information different from the authentication structure is recorded. The authentication structure is a resist structure 5 whose pattern interval is less than 10 nanometer, and which is formed by performing resist destruction of a resist pattern 8 to be formed of a plurality of columnar pillars which are nano-order patterns formed on a base 6. The authentication structure is incorporated in the information recording part through a process included in manufacturing processes of the information recording part.
