The present invention provides an adhesive composition, an adhesive, and an adhesive sheet which are excellent in durability without adversely affecting an adherend such as a transparent conductive film. In order to solve the above problems, there is provided an adhesive composition comprising a weight average molecular weight of from 1.4 to 2.5 million, and a monomer having a hydroxyl group and a monomer having an alicyclic structure as a monomer unit constituting the polymer. And a (meth) acrylate polymer (A) having a carboxyl group, an isocyanate bridging agent (B), and a decane coupling agent (C) having a mercapto group, (meth) acrylate polymer (A), The monomer unit constituting the polymer contains 1% by mass to 5% by mass of a monomer having a hydroxyl group and 0.1% by mass to 0.8% by mass of a monomer having a carboxyl group. |
