    • PROBLEM TO BE SOLVED: To provide a drying device for manufacturing a pressure-sensitive adhesive tape capable of carrying out drying of a coating agent on a tape base material further positively without enlarging a whole of the device, and usable in manufacturing of pressure-sensitive adhesive tapes with different drying treatment times during manufacturing.
      SOLUTION: The drying device for manufacturing the pressure-sensitive adhesive tape dries the coating agent S applied to at least one face of the tape base material T to manufacture the pressure-sensitive adhesive tape formed with a pressure-sensitive adhesive layer on the band-like tape base material T. It includes cylindrical bodies 310a, 310b spirally winding the long tape base material T sent in the longitudinal direction in a slidable state from a one end side to another end side, and the cylindrical bodies 310a, 310b are formed with a multiplicity of vent holes 311a, 311b passing warm or hot air from inner sides to outer sides on whole circumferences of peripheral walls wound with the tape base material T.
