Provided is a self-rolling pressure-sensitive adhesive tape which can roll by itself and which makes it possible to easily recover a roll, which has been formed by applying the tape to an adherend and then making the tape roll by itself, from the adherend without necessitating a tool or device that must be separately prepared. This self-rolling pressure-sensitive adhesive tape is a pressure-sensitive adhesive tape which can roll by itself when irradiated with an actinic radiation and then heated and which comprises a base material layer and a pressure-sensitive adhesive layer. When applying a release sheet onto the adhesive surface of the pressure-sensitive adhesive layer, irradiating the resulting tape with an actinic radiation from the release sheet side and thereafter peeling off the release sheet, the arithmetic mean roughness (Ra) of the adhesive surface of the pressure-sensitive adhesive layer which has been cured by irradiation with the actinic radiation is 31.5nm or more. Further, the r/L ratio is 0.0001 to 0.999 [wherein L(mm) is the length in the rolling direction, and r(mm) is the diameter of a roll formed by self-rolling]. |
