The present invention provides an adhesive composition, an adhesive, and an adhesive sheet having high adhesion to optical members such as polarizing plates and excellent durability. In order to solve the above-mentioned problems, an adhesive composition is provided which includes, as a monomer unit constituting a polymer, a (meth) acrylate polymer (A) containing a monomer having an alicyclic structure, and having an average weight The molecular weight is from 800,000 to 3 million; the bridging agent (B); and the silane coupling agent (C) have a mercapto group as a functional group that reacts with an organic material. |
