A surface of the conceal layer 14 comprises a lottery part 16, and a main face at the lottery part 16 side comprises a transparent interlayer separation layer 18. A transparent synthetic resin layer 20 is formed on at least a part of one of the main faces of the interlayer separation layer 18, and is adhered to the base material 14 by the adhesion force of the interlayer separation layer 18. An adhesive layer 22 is formed on the main face of the synthetic resin layer 20, and the synthetic resin layer 20 and the adhesive layer 22 are transparent or semitransparent. |
