PROBLEM TO BE SOLVED: To provide a seal which is stuck to an object to be sealed and clearly reveals illicit peeling, and which leaves no opaque layer or adhesive layer released from the seal on the object when the seal is removed from the object, or leaves those layers to be easily removed from the object. SOLUTION: A warning 11 is printed with a release agent on one surface of a transparent or translucent surface sheet 10 to form a release portion 12 which can be easily released. An opaque layer 13 is formed in the release portion 12 side of the surface sheet 10, and an adhesive layer 14 is formed on the outer surface of the opaque layer 13. The adhesive layer 14 enables the surface sheet 10 to be adhered to and released from the object 15. The adhesive layer is formed in such a manner that on peeling the sheet, the adhesive layer in the release portion with the corresponding opaque layer can be peeled from the surface sheet, and that the adhesive layer does not remain on the object on peeling from the object, or can be removed from the object by rubbing with fingers.
