Abstract
Provided is a novel double-sided adhesive sheet for image display device which can be bonded to the adhesion surface in close contact without space therebetween although there is a step due to printing or the like on the adhesion surface to be bonded to the adhesive sheet. The double-sided adhesive sheet for image display device 1 of the invention is a sheet to bond any two adherends selected from a surface protective panel 2, a touch panel 3, and an image display panel, and the sheet is characterized in that at least one of the adherends (surface protective panel 2) has a stepped portion 2b on an adhesion surface 2a to adhere to the double-sided adhesive sheet 1 and the surface shape of the bonding surface 1a of the double-sided adhesive sheet 1 to be bonded to the adhesion surface 2a is shaped in accordance with the surface shape of the adhesion surface 2a.
