Abstract
Provided is a polysulfide-based pressure-sensitive adhesive tape that is excellent in oil resistance and the like, and sufficiently has a pressure-sensitive adhesive strength. The polysulfide-based pressure-sensitive adhesive tape of the present invention includes a pressure-sensitive adhesive layer formed from a polysulfide-based pressure-sensitive adhesive composition containing a sulfur-containing polymer, wherein the sulfur-containing polymer has a disulfide structure represented by —S—S— in a main chain thereof, and wherein a ball number for tack of the pressure-sensitive adhesive layer measured by an inclined ball tack test method (inclination angle: 30°) specified in JIS Z 0237 at a temperature of 23° C. and a humidity of 65% is 2 or more.
