The present invention provides an adhesive composition, an adhesive, an adhesive sheet, and an optical film with an adhesive layer that exhibit excellent antistatic properties, have excellent durability, are less likely to warp a display panel, and hardly cause heat unevenness. A monomer unit constituting a polymer contains an alicyclic structure-containing monomer (a1), an aromatic ring-containing monomer (a2), and a hydroxyl group-containing monomer (a3), and also contains a carboxyl group-containing monomer. An adhesive composition containing a (meth) acrylic acid ester copolymer (A), a crosslinking agent (B), and an antistatic agent (C), wherein the antistatic agent (C) is at room temperature An adhesive composition which is a solid and is an ionic compound composed of a nitrogen-containing heterocyclic cation and a halogenated phosphate anion.
