Claim 0:
1. A double-sided pressure-sensitive adhesive tape, comprising:
a base material layer formed of an unfoamed resin film containing a polyurethane-based resin as a main component; 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.
