The present invention provides a pressure-sensitive adhesive tape capable of exhibiting excellent adhesive property, and of inhibiting deformation of an adherend fixed with this pressure-sensitive adhesive tape, even under a high temperature or low temperature environment. The pressure-sensitive adhesive tape is one having a pressure-sensitive adhesive layer including a pressure-sensitive adhesive composition containing a (meth)acrylic polymer, wherein the (meth)acrylic polymer is obtained by copolymerization of a monomer mixture containing, at least, 60 to 96% by weight of a (meth)acrylic acid alkyl ester having an alkyl group with 4 to 12 carbon atoms, 2 to 10% by weight of a carboxyl group-containing monomer, and 2 to 8% by weight of an ethylenically unsaturated monomer having no carboxyl group, whose homopolymer has a glass transition temperature of 50 to 190° C. as monomer components, and the pressure-sensitive adhesive layer has a gel fraction of 0 to 30% by weight.
