A waterproof and airtight double-sided pressure-sensitive adhesive tape includes a substrate and a pressure-sensitive adhesive layer on the both surfaces thereof, wherein the substrate is a rubber-made sheet; and the surface of at least one of the pressure-sensitive adhesive layers is protected by a release liner having elongation properties. It is preferable that the rubber-made sheet as the substrate has an elongation at the time of breakage (distance between two gage marks: 40 mm, drawing rate: 300 mm/min) of from 200 to 1,200 % in both the longitudinal direction and the cross direction and a stress under 100 % elongation (distance between two gage marks: 40 mm, drawing rate: 50 mm/min) of from 10 to 100 N/cm 2 in both the longitudinal direction and the cross direction. |
