The present invention provides a pressure-sensitive adhesive that can realize a pressure-sensitive adhesive layer that satisfies adhesive performance, has a low dielectric constant, and has high humidity resistance. A monomer component containing 30 to 99.5% by weight of an alkyl (meth) acrylate having an alkyl group having 10 to 18 carbon atoms at an ester terminal and 0.5 to 50% by weight of a cyclic nitrogen-containing monomer is polymerized. A pressure-sensitive adhesive comprising a (meth) acrylic polymer obtained by the method. [Selection] Figure 1 |
