A PRESSURE-SENSITIVE ADHESIVE TAPE PACKAGE (10) IS DISCLOSED IN WHICH WHILE EASINESS IN APPLYING THE ADHESIVE TAPE IS PURSUED, AN EFFECT OF SAVING IN RESOURCES CAN BE OBTAINED. THE PRESSURE-SENSITIVE ADHESIVE TAPE PACKAGE (10) ACCORDING TO THE PRESENT INVENTION 10 ACCOMMODATES AN ADHESIVE TAPE (14) HAVING A SUPPORT (18) AND AN ADHESIVE AGENT LAYER (12) PROVIDED ON ONE SURFACE OF THE SUPPORT (18), AND INCLUDES A RELEASE SHEET (16) RELEASABLY ATTACHED TO THE ADHESIVE AGENT LAYER (12). MOREOVER, IN THE PRESSURE-SENSITIVE ADHESIVE TAPE PACKAGE (10), THE RELEASE SHEET (16) IS BENT ALONG A PREDETERMINED BENDING LINE WITH THE ADHESIVE TAPE (14), AND THE ADHESIVE TAPE (14) IS SEALED INSIDE OF THE BENT RELEASE SHEET (16). ACCORDING TO SUCH A CONFIGURATION, THE CONVENTIONALLY EXISTING PACKAGE SEPARATED FROM THE RELEASE SHEET (16) CAN BE ELIMINATED. MOREOVER, WHEN THE RELEASE SHEET (16) IS OPENED WHILE THE RELEASE SHEET (16) IS RELEASED FROM THE ADHESIVE AGENT LAYER (12) OF THE ADHESIVE TAPE (14), AN HALF OF THE ADHESIVE AGENT LAYER (12) IS EXPOSED; ACCORDINGLY, APPLICATION TO THE PORTION FOR APPLICATION IS EASY.
