摘要：
A plate body 2, multiple hologram layers 3 are provided in the thickness direction of the plate body 2, and at least one of the multiple hologram layers 3 is formed of spirally continuous hologram bands 4. Erasure areas 4A and 4B and non-erasure areas 4C and 4D of the hologram band 4 are provided in the length direction of the hologram band 4. Non-erasure areas 4E and 4F of the hologram band 4 are formed on both sides in the direction orthogonal to the length direction of the hologram band 4 in the erasure areas 4A and 4B.
