Abstract
[An object of the present invention is] to provide transfer tape that maintains strong adhesive strength but can be reliably cut at a stipulated position. The adhesive film contains needle-shaped particles. If the adhesive strength is made high, then the adhesion between the adhesive ingredients is increased, thus forming a film that is difficult to cut. If a force is applied to the band-shaped ribbon in a direction outside the plane in which the adhesive coating is applied, then the film of the adhesive coating becomes thin and the needle-shaped particles rupture the film and cut the adhesive film. Moreover, the cut adhesive film draws the cut end to the needle-shaped particles, and as a result it is cut completely without stringiness.
