A pressure-sensitive adhesive tape package is provided. The pressure-sensitive adhesive tape package accommodates an adhesive tape having a support and an adhesive agent layer provided on one surface of the support, the adhesive tape being bent into a first portion and a second portion such that the adhesive agent layer faces outward. Moreover, the pressure-sensitive adhesive tape package can include a first release sheet releasably attached to the adhesive agent layer of the first portion of the adhesive tape, and a second release sheet releasably attached to the adhesive agent layer of the second portion of the adhesive tape to seal the adhesive tape with the first release sheet between the first and second release sheets. In this configuration, the conventionally existing package can be eliminated. Moreover, when the second release sheet is removed from the adhesive agent layer of the second portion of the adhesive tape, half of the adhesive agent layer is exposed.
