PROBLEM TO BE SOLVED: To provide a sealing sticker which does not damage the appearance beauty of an article to be sealed, prevents a third party from opening a sealed bag or box without permission, leaves trace when opened, and allows a concerned party to easily confirm that an article is not a forgery when the concerned party opens it. SOLUTION: The sealing sticker includes: a base material sheet; an adhesion preventing layer formed in at least part of the surface of the base material sheet; a stress light-emitting layer containing a stress light-emitting material in at least part of the upper surface of the adhesion preventing layer; a pressure sensitive adhesive layer formed on the base material backside; and a peeling sheet formed to cover the pressure sensitive adhesive layer. The peeling sheet is peeled from the pressure sensitive adhesive layer to expose the pressure sensitive adhesive layer, and the sealing sticker is fixed to an article to be sealed by the exposed pressure sensitive adhesive layer. When the sealing sticker fixed to the article is peeled, the stress light-emitting layer is peeled or destroyed by an external stress applied to the sealing sticker, and thus light of an optional color is emitted.
