PROBLEM TO BE SOLVED: To provide a resin molding which, when a pressure-sensitive adhesive tape is stuck thereto, does not decrease the holding power of the adhesive sheet with time even when the molding contains a plasticizer. SOLUTION: The same plasticizer as that contained in the resin molding is incorporated in advance into the pressure-sensitive adhesive layer of the adhesive sheet to eliminate the concentration gradient of the plasticizer between the resin molding and the pressure-sensitive adhesive layer; thus, the migration of the plasticizer from the molding to the adhesive layer is prevented.
