PROBLEM TO BE SOLVED: To provide a rolled material of a pressure-sensitive adhesive tape, which can be stably produced without the necessity for complicated control in the industrial production and is suitable for applications where air permeability is required. SOLUTION: This rolled material of a pressure-sensitive adhesive tape comprises a material made by laminating a pressure-sensitive adhesive layer on one side of a base material having fine voids and an interlaminar strength of 1.9 N/cm<2> or higher. The material has no permeability in a state before being rolled into a roll, and reveals permeability only when it is unrolled and the pressure-sensitive adhesive layer is peeled for use.
