PURPOSE:The titled sheet, obtained by laminating a reaction product between a liquid diene based polymer and a polyisocyanate on a base material, having improved tackiness and creep resistance, capable of withstanding repeated use of peeling, reclaimable for use, and useful for dust removing tools. CONSTITUTION:A double-sided adhesive sheet obtained by laminating an adhesive layer consisting of a reaction product between (A) a liquid diene based polymer, e.g. polybutadiene homopolymer having 600-10,000 number-average molecular weight, having at least two active hydrogen groups, e.g. hydroxyl groups, in the molecule on at least one side of a base material, e.g. a polyester film.
