PROBLEM TO BE SOLVED: To provide an adhesive tape which prevents corrosion of a metal surface, suppresses foaming by outgassing from a resin panel in a high temperature environment, prevents peeling near an edge in a high temperature environment and leaves no glue residue when the tape is peeled.SOLUTION: A double-sided adhesive tape is provided, which has an adhesive layer comprising an acrylic adhesive composition on both surfaces of a substrate, and which is used for bonding a transparent resin member and a metal surface. The substrate comprises a resin film substrate having a thickness of 5 to 45μm. The adhesive layer to be stuck to the transparent resin member comprises an acrylic copolymer containing a carboxyl group-containing monomer as a monomer component and shows a loss tangent of 0.15 to 0.30 at 80°C in a viscoelasticity spectrum; and the adhesive layer to be stuck to the metal surface comprises an acrylic copolymer having 1 mass% or less of the content percentage of a carboxyl group-containing monomer in the monomer component, and has a gel fraction of 30 to 90 mass%. |
