A pressure-sensitive adhesive tape package is disclosed in whichwhile easiness in applying the adhesive tape is pursued, an effect ofsaving in resources can be obtained. The pressure-sensitive adhesivetape package according to the present invention 10 accommodates anadhesive tape 14 having a support 18 and an adhesive agent layer 12provided on one surface of the support 18, and includes a release sheet16 releasably attached to the adhesive agent layer 12. Moreover, in thepressure-sensitive adhesive tape package 10, the release sheet 16 is bentalong a predetermined bending line with the adhesive tape 14, and theadhesive tape 14 is sealed inside of the bent release sheet 16.According to such a configuration, the conventionally existing packageseparated from the release sheet can be eliminated. Moreover, whenthe release sheet 16 is opened while the release sheet 16 is released fromthe adhesive agent layer 12 of the adhesive tape 14, an half of theadhesive agent layer 12 is exposed; accordingly, application to theportion for application is easy.
