<p>PROBLEM TO BE SOLVED: To provide an adhesive tape which has excellent adhesiveness in a wide temperature range while suppressing the expansion of a moisture-permeable waterproof sheet.SOLUTION: In an adhesive tape 1 which includes a substrate 2, a target-side adhesive layer 3 laminated on one surface of the substrate 2, and a sheet-side adhesive layer 4 laminated on the other surface of the substrate 2, and has an expansion coefficient of a moisture-permeable waterproof sheet of 0.5% or less when measured after being heated at 60°C for 5 days in a state where the target-side adhesive layer 3 is stuck to an aluminum plate and the sheet-side adhesive layer 4 is stuck to the moisture-permeable waterproof sheet, the target-side adhesive layer 3 contains a first rubber component containing 40-93 mass% of butyl rubber and 7-60 mass% of polyisobutylene, and a first softener mixed in the target-side adhesive layer 3 at a mixed ratio of 82-128 pts.mass with respect to 100 pts.mass of the first rubber component and having a kinematic viscosity at 40°C of 100-9,000 mm/s.</p> |
