The present invention addresses the problem of providing a double-sided adhesive tape which has proper impact resistance and can be broken down upon the application of a certain level of force, and of which a residual material remaining on the surface of an object on which the adhesive tape has been attached, e.g., a glue, can be removed readily. The present invention is a double-sided adhesive tape comprising a foam base material, a resin film laminated on one surface of the foam base material, and adhesive agent layers respectively laminated on the surface of the resin film and on the other surface of the foam base material, wherein the foam base material has a density of 0.45 g/cm 3 or less and interlayer strength of 10 N/cm or more, and wherein, when an adhesive tape produced by forming a 25 μm-thick adhesive agent layer on a 25 μm-thick PET base material is pressed over an aluminum plate back and forth one time using a 2 kg roller under the conditions having a temperature of 23°C and a relative humidity of 65% RH, and is then allowed to stand for 1 hour in an environment having a temperature of 23°C and a relative humidity of 50% RH, the adhesive tape has a 180°peel adhesion of 10 N/20 mm or more at a peel rate of 300 mm/min. |
