PROBLEM TO BE SOLVED: To obtain an adhesiveness-improving agent providing an adhesive composition having excellent adhesive strength, peelability at a constant load, and stain resistance by being formulated with a (meth)acrylic polymer, and having excellent compatibility with the (meth)acrylic polymer. SOLUTION: The adhesiveness-improving agent contains a composite polymer which is obtained by dissolving and polymerizing a (meth)acrylic monomer with an unhydrogenated adhesiveness-imparting resin, and in which at least a part of the unhydrogenated adhesive-imparting resin is copolymerized with the (meth)acrylic monomer.
