Title: DOUBLE-SIDED ADHESIVE TAPE
Abstract:
The purpose of the present invention is to provide a double-sided adhesive tape having excellent stress relaxation properties and impact resistance, as well as excellent reworkability on both adhesive surfaces. This double-sided adhesive tape includes a foam substrate, and a first adhesive layer and a second adhesive layer which are respectively provided to one side and the other side of the foam substrate, wherein a first resin layer and a second resin layer having a tensile breaking point stress of 4 MPa or greater are disposed between the foam substrate and the first adhesive layer and between the foam substrate and the second adhesive layer, respectively.
