Abstract:
A problem to be solved by the present invention is to provide an adhesive tape capable of maintaining excellent adhesive strength for a long time even when sweat, sebum, an alcohol, or the like adheres thereto. The present invention relates to an adhesive tape having an adhesive layer containing an acrylic adhesive, the acrylic adhesive including an acrylic copolymer, in which the acrylic copolymer contains, as constituent components, (A) 5 to 20% by mass of a carboxyl group-containing monomer, (B) 0.01 to 1% by mass of a hydroxyl group-containing monomer, and (C) one or two or more selected from the group consisting of other alkyl (meth)acrylate monomers and alicyclic monomers, in which the average number of carbon atoms of saturated hydrocarbon groups included in the monomers (C) is 4 or less.
