A process for manufacturing easily portable and multi-layered adhesive tape roll is described. The flat piece of easily portable and multi-layered adhesive tape is formed by compressing the adhesive tape roll having circular shape or other shapes. The adhesive tape roll is compressed and cohered during the compressing step. A stiff interfacial layer, for example, having adhesion by adhering two innermost adhesive surfaces, by providing a stronger adhesion material, by inserting a stiff and solid material, or a stiff and solid material coated with a strong adhesion material, is applied to the symmetry plane of the adhesive tape during the compressing step. The preferential material of the high adhesion material is a cyanoacrylate adhesive or an epoxy adhesive.
