An object of the present invention is to provide a pressure-sensitive adhesive composition having a long port life capable of forming an adhesive sheet excellent in adhesive properties (adhesiveness, light peeling property at high-speed peeling, re-peeling property) and antistatic property. The adhesive composition of this invention is a (meth) acrylic-type polymer comprised by the (meth) acrylic-type monomer which has a C1-C14 alkyl group and the (meth) acrylic-type monomer which has a hydroxyl group as a raw material monomer, an alkali metal salt, And a catalyst having iron as an active center, wherein the methacryl monomer having the hydroxyl group is 6 parts by weight based on 100 parts by weight of the (meth) acrylic monomer having an alkyl group having 1 to 14 carbon atoms. It is characterized by containing more than a part. |
