Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide double-sided adhesive tape that has excellent stress relaxation and impact resistance, excellent reworkability on both adhesive surfaces, and that can easily be wound into a roll shape while suppressing the occurrence of wrinkles or folds. This double-sided adhesive tape includes a foam base material, and a first adhesive layer and a second adhesive layer on each side of the foam base material, wherein a first resin layer and a second resin layer having a tensile break point stress of 4 MPa or greater are disposed between the foam base material and the first adhesive layer and between the foam base material and the second adhesive layer, and the first resin layer and/or the second resin layer has a tensile modulus of elasticity of 50 MPa or less.
