Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a double-sided adhesive sheet which is capable of bonding two members, e.g. bonding a styrene foam onto the surface of a vinyl chloride pipe, and enables easy release of one of the members and easy reuse of the released member. SOLUTION: The double-sided adhesive sheet has a weak adhesive layer and a strong adhesive layer whose adhesive force is ≥1.3 times larger than that of the weak adhesive layer. The double-sided adhesive sheet is manufactured by laminating the weak adhesive layer and the strong adhesive layer substantially without any substrate intervening between them.
