PROBLEM TO BE SOLVED: To provide an acrylic pressure-sensitive adhesive composition which can attain a high cohesive power by introducing a cross-linked structure immediately after application without using a cross-linker and is easily recyclable. SOLUTION: The pressure-sensitive adhesive composition contains a copolymer of an acrylic monomer, an ethylenic unsaturated monomer having an electrophilic site, and an ethylenic unsaturated monomer and a copolymer of an ethylenic unsaturated monomer having a nucleophilic site and an acrylic monomer and/or an ethylenic unsaturated monomer, or the composition contains an acrylic copolymer prepared by using an ethylenic unsaturated monomer having a nucleophilic site as a copolymerization component and a copolymer prepared by using an ethylenic unsaturated monomer having an electrophilic site as a copolymerization component.
