A double-sided adhesive tape having an adhesive layer on both sides of a foam base material, wherein the interlayer strength of the foam base material is 12 N / cm or more and 25% compressive strength is 30 to 170 kPa, and the pressure sensitive adhesive layer is a (meth) acryl having 4 to 12 carbon atoms. Double-sided adhesion also at the time of bonding of rigid bodies with the double-sided adhesive tape which consists of an acryl-type copolymer which has a vinyl monomer which has a rate and a carboxy group as a monomer component, and an acrylic adhesive composition containing superposition | polymerization rosin-ester tackifying resin. Excellent adhesion between the tape and the adherend, rework aptitude and re-peelability can be realized, and water immersion can be effectively prevented. |
