    Abstract: A laminated body includes: an antireflection film; and a protection film bonded onto the antireflection film. The adhesive layer is a layer with a material formed by cross-linking, with a cross-linking agent (B), and a (meth)acrylic acid ester copolymer. The (meth)acrylic acid ester copolymer (A) is a copolymer formed by polymerizing monomer components including, in relation to the total amount of the monomer components set at 100% by mass, 70 to 98% by mass of a (meth)acrylic acid alkyl ester monomer (a) including a noncyclic alkyl group containing 4 to 9 carbon atoms, 1.5 to 25% by mass of a (meth)acrylic acid ester monomer (b) containing an aliphatic ring, and 0.5 to 5% by mass of a (meth)acrylic-based monomer (c) containing a functional group exhibiting reactivity with the cross-linking agent (B). The area proportion of the components each having a molecular weight of 100,000 or less, is less than 3.0%.
