Abstract: An adhesive tape structure can suppress protrusion of adhesive agent and blocking. The adhesive tape structure includes adhesive tapes each provided with a base film, an adhesive film, and a cover film laminated in this order, and a linking tape linking the adhesive tapes and configured such that the cover films of the adhesive tapes are integrally released. The adhesive tapes each have a part having a predetermined length completely removed from an edge portion of the adhesive film on a release initiation side in a cover film release direction; the adhesive tape thus has gaps in the edge portions of the adhesive films.
