Abstract: A double-sided pressure-sensitive adhesive tape having excellent impact resistance, excellent reworkability, and excellent alcohol resistance. The double-sided pressure-sensitive adhesive tape includes: a base material layer; and pressure-sensitive adhesive layers arranged on both surface sides of the base material layer, wherein the pressure-sensitive adhesive layers are each formed from a pressure-sensitive adhesive composition, wherein the pressure-sensitive adhesive composition contains at least one kind selected from the group consisting of a monomer component (m) and a polymer component (P) obtained by polymerizing the monomer component (m), wherein the monomer component (m) contains 50 wt % or more of butyl (meth)acrylate, wherein a ratio of a thickness of the base material layer to a total thickness of the double-sided pressure-sensitive adhesive tape is less than 35%, and wherein the double-sided pressure-sensitive adhesive tape has a force, which is generated at 100% strain at 23° C. and 50% RH, of from 30 N/m to 150 N/m.
