A junction band with high tensile strength in order to suppress rupture of a ground fabric from the junction band. Provided is a hollow-weave base fabric that includes a hollow-weave section (111) with a dual layer structure containing a first fabric layer and a second fabric layer, and a junction band (112) formed continuously from threads which form the hollow-weave section. The junction band comprises a first junction structure section (121), in which a structure of two layers is formed by the alternating positional relationship of a first continuation thread that extends from the first fabric layer of the hollow-weave section to the first junction structure section and a second continuation thread that extends from the second fabric layer of the hollow-weave section to the first junction structure section. The first junction structure section comprises at least one free perpendicular thread (400, 400′) within the two-layer structure of the first junction structure section, and the free perpendicular thread extends in a direction perpendicular to the first continuation thread and the second continuation thread and does not form part of the structure of two layers of the first junction structure section.
