A pressure-sensitive adhesive tape package which can contribute to resource saving while attaining easy application of the pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape package (10) holds therein a pressure-sensitive adhesive tape (14) comprising a support (18) and a pressure-sensitive adhesive layer (12) disposed on one side of the support (18), and is constituted of a release sheet (16) that is adherent in a strippable state to the pressure-sensitive adhesive layer (12). The pressure-sensitive adhesive tape package (10) has a configuration in which the release sheet (16) has been folded along a given fold line together with the pressure-sensitive adhesive tape (14) so that the pressure-sensitive adhesive tape (14) is enclosed inside the folded release sheet (16). This configuration can omit the conventional package independent of a release sheet. When the package is opened while stripping the release sheet (16) from the pressure-sensitive adhesive layer (12) of the pressure-sensitive adhesive tape (14), half of the pressure-sensitive adhesive layer (12) gets exposed to thereby facilitate application to a part to be covered with the tape.
