PROBLEM TO BE SOLVED: To provide a double-sided adhesive tape made of rubber, capable of readily releasing and separating a bonded material without injuring a substrate, etc., when it is required to release the bonded material after wood products are adhesively bonded to each other or the wood product is adhesively bonded to a glass product, etc. SOLUTION: The double-sided adhesive tape comprises a tape-like base material 10 made of a rubber, adhesive layers 11 and 12 provided on both sides of the base material 10 made of the rubber and release auxiliary members 13 bonded in the longitudinal direction of the upper surface of either one adhesive layer 11 or the upper surfaces of both adhesive layers 11 and 12. When release is carried out and the base material 10 made of rubber is pulled together with the release auxiliary member 13, the base material 10 made of rubber is readily expanded by the release auxiliary member 13 and the tape width becomes gradually narrow and the adhesive area becomes smaller and the tape is readily released.
