PROBLEM TO BE SOLVED: To provide a double-sided adhesive tape which is easy to peeling the bonded portion and, at the same time, cannot be bonded again once peeled. SOLUTION: The double-sided adhesive tape 1 is composed of a first base layer 4 and a second base layer 5 which are peelable from each other and cannot be bonded again after peeling, and a first adhesive layer 3 and a second adhesive layer 6 which are attached on the opposite surfaces of the bonded portion of the above base layers, respectively. For example, when the tape is used in sealing the packaging of a parcel, the recipient can easily open the parcel since the tape can be peeled from the bonded portion. Further, once the bonded portion is peeled, it cannot be bonded again, and thus if a third person should have seen the contents before the receipt of the parcel by the addressee, such a deed done can easily be grasped.
