Abstract
An adhesive composition according to the present invention is an adhesive composition whose main component is a polymer obtained by copolymerization of a monomer composition, which monomer composition contains styrene, (meth)acrylic ester having a cyclic structure, and alkyl (meth)acrylate having a chain structure. The polymer thus having a styrene block segment allows improvement of thermal resistance, adhesive strength in a high temperature environment, alkaline resistance, and easiness in stripping following a high temperature process of the adhesive composition. As such, an adhesive composition is provided, which has high thermal resistance, adhesive strength in the high temperature environment, and alkaline resistance, and further which can easily carry out stripping of the adhesive composition after a high temperature process has been carried out to the adhesive composition.
