Fastening tape

The invention provides a fastening tape, by which it is possible to prevent foam from intruding into an area of fastening elements, to improve flexibility of the fastening tape in the longitudinal direction and the lateral direction, and to facilitate an increase in attachment between the fastening tape and the foam. The fastening tape comprises: an elongated substrate and a plurality of fasteningcells on a surface of the substrate, wherein each of at least some of the fastening cells comprises: a fastening element array; a pair of longitudinal walls and a pair of transverse walls at least partially surrounding the fastening element array; at least one slit provided in an upper portion of the pair of transverse walls; and a semi-fastening element at least partially filling the slit, wherein at least some of the fastening cells which are adjacent to each other in a longitudinal direction are separated from each other by an open space extending across the substrate in a lateral direction, wherein the semi-faste
