Abstract

An acrylic pressure-sensitive adhesive tape includes a core layer and a surface layer provided on one or both surfaces of the core layer. The core layer contains an acrylic polymer (A). The surface layer contains 100 parts by mass of an acrylic polymer (B) and 1 to 70 parts by mass of a (meth) acrylic polymer (C) that has a weight average molecular weight of 1000 or more and less than 30000 and that has a terpene skeleton in its side chain. The (meth) acrylic polymer (C) is a polymer having a weight average molecular weight smaller than that of the acrylic polymer (B) as a pressure-sensitive adhesive composition and functions as a tackifying resin.
