Beschreibung
Zusammenfassung:	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 adhesivesurfaces. 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 foamsubstrate, 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. 本发明的目的在于，提供具有优异的应力松弛性和耐冲击性且两个粘合面的再加工性优异的双面粘合带。本发明是一种双面粘合带，其为具有发泡体基材且在上述发泡体基材的两面分别具有第一粘合剂层和第二粘合剂层的双面粘合带，其中，在上述发泡体基材与上述第一粘合剂层之间、以及上述发泡体基材与上述第二粘合剂层之间，分别具有拉伸断裂点应力为4MPa以上的第一树脂层和第二树脂层。
