PROBLEM TO BE SOLVED: To provide a multilayer double-sided pressure-sensitive adhesive sheet which is repeelable from an adherend without leaving any adhesive residue by lowering and eliminating pressure-sensitive adhesive strength so as to make the sheet be in an easily peelable state with irradiation of an active energy ray after bonding and at a desired time, a laminate body using the multilayer double-sided pressure-sensitive adhesive sheet, and a display device with a touch panel attached thereto using the multilayer double-sided pressure-sensitive adhesive sheet.SOLUTION: A multilayer double-sided pressure-sensitive adhesive sheet has at least three layers of pressure-sensitive adhesive layers of a first outermost pressure-sensitive adhesive layer 11, a second outermost pressure-sensitive adhesive layer 12, and an intermediate pressure-sensitive adhesive layer 13. The first outermost pressure-sensitive adhesive layer 11 is an active energy ray curable pressure-sensitive adhesive layer containing a base polymer (A), a crosslinking agent (B), and a polymerizable unsaturated group-containing monomer (C), the second outermost pressure-sensitive adhesive layer 12 contains a polymerization initiator (D) to initiate a polymerization reaction of the polymerizable unsaturated group-containing monomer (C), and the content of the polymerization initiator (D) is 1.0-5.0 pts.mass. based on 100 pts.mass of a pressure-sensitive adhesive composition of the first outermost pressure-sensitive adhesive layer 11. |
