PURPOSE:To obtain an indicator body the genuineness of which can be examined at a glance. CONSTITUTION:In an indicator 1, a hologram part 4 regenerating different images by being observed at different angles is provided in proximity to an optical variable ink part 3 producing different hues by being observed at different angles, and the hologram image and the hue of a reflected light are simultaneously changed according to an observing angle. In this manner, the genuineness of the indicator 1 can be easily examined at a glance. |
