摘要：An acrylic pressure-sensitive adhesive tape includes a core layer and a surfacelayer provided on one or both surfaces of the core layer. The core layer contains anacrylic 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 averagemolecular weight of 1000 or more and less than 30000 and that has a terpene structurein its side chain. The (meth)acrylic polymer (C) is a polymer having a weight averagemolecular weight smaller than that of the acrylic polymer (B) as a pressure-sensitiveadhesive composition and functions as a tackifying resin.
