The present invention provides an adhesive tape containing heat-expandable microspheres, which has excellent peelability after heating and has less paste residue on an adherend. The adhesive tape of the present invention includes a substrate and an adhesive layer disposed on at least one side of the substrate. The adhesive layer includes thermally expandable microspheres, and the adhesive tape is heated at a temperature of 3 ° C in a thermomechanical analysis. When heating is performed per minute, the deformation starting point is set to point A, and the point where the amount of deformation of the adhesive tape becomes the largest after the point A is expanded is set to point C, and the amount of deformation from point A to point C becomes When half of the deformation amount of the point C is set to the point B, the time from the point A to the point B is 45 seconds to 200 seconds. |
