To provide a baseless double-sided adhesive sheet or tape that is configured such that adhesive does not exude during storage, or moreover during slitting to a predetermined size, or the like, and that is also capable for exhibiting the desired performance of having a cohesive force that resists peeling, without sacrificing the initial adhesive strength, and to provide a method for manufacturing the same. In the baseless double-sided adhesive sheet or tape, an adhesive layer formed from an adhesive serves as a center layer, and adhesive layers and formed from an adhesive are layered onto a front face and a rear face of the adhesive layer serving as the center layer. Fibers are least dispersed in the adhesive layer serving as the center layer, and the adhesive layer serving as the center layer between the adjacent adhesive layers has a relatively high fiber density and relatively low flowability.
