Abstract:
PROBLEM TO BE SOLVED: To provide a double-sided adhesive tape for waterproofing, waterproofness of which is not deteriorated even when its width is reduced.SOLUTION: The double-sided adhesive tape for waterproofing comprises: a substrate 3 formed of a non-foamed elastomer; and adhesive layers 2 comprising an adhesive which are placed on both of front and back surfaces of the substrate 3. The substrate 3 has a thickness of 50 μm or more and 1000 μm or less, and the substrate 3 satisfies at least one condition of the following two: that a Young's modulus determined from a load-displacement curve when an indenter is indented by a nanoindentation method is in a range of 5 to 500 MPa; and that an indentation depth when an indenter is indented by a nanoindentation method is in a range of 4 to 15 μm.
