An object of the present invention is to provide a pressure-sensitive adhesive composition, a pressure-sensitive adhesive and a pressure-sensitive adhesive sheet which are excellent in both blister resistance and anti-wet heat resistance. As a means for solving such a problem, there is known a method in which, as a monomer unit constituting a polymer, a (meth) acrylic acid alkyl ester, a reactive functional group containing monomer having a reactive functional group in the molecule, and a (meth) acrylic acid ester polymer (A) and a cross-linking agent (B). |
