Abstract

A pressure-sensitive adhesive of the invention include a (meth)acryl-based polymer obtained by polymerization of a monomer component including 19 to 99.5% by weight of an alkyl (meth)acrylate having a branched alkyl group of 10 to 24 carbon atoms at an ester end. The pressure-sensitive adhesive has a satisfactory level of adhesive performance and can form a pressure-sensitive adhesive layer with a lower dielectric constant.
