An object of the present invention is to provide a pressure-sensitive adhesive composition that forms a pressure-sensitive adhesive layer that has excellent adhesiveness at temperatures from about -30 ° C to room temperature and has reworkability at about -50 ° C or lower. is there. The pressure-sensitive adhesive composition of the present invention is a pressure-sensitive adhesive composition comprising an acrylic polymer obtained by polymerizing a monomer component, or a partial polymer of the monomer component, wherein the monomer component is ( (Meth) acrylic acid C 10-13 alkyl ester and a polar group-containing monomer excluding a carboxyl group, and the content of the (meth) acrylic acid alkyl ester is 40% by weight or more and 80% by weight based on the total amount of the monomer components. %, The content of the polar group-containing monomer is 7% by weight or more based on the total amount of the monomer components, and the total content of the polar group-containing monomer and the alicyclic monomer in the monomer component is It is characterized by being 15% by weight or more based on the total amount of the monomer components.
