To provide a bound band-shaped body that does not deform when it is bound, and an apparatus for binding the band-shaped body with a tape, which can be miniaturized and does not deform the band-shaped body upon binding it.

In front of an insertion slot for inserting the band-shaped body, a strip of single-side-adhesive tape is held with its non-adhesive side turned to the slot, and the band-shaped body to be bound is inserted, as the tape is caught by it, into the slot. When the inserted band-shaped body pushes down a detection projection of a clamp arranged in the slot, the clamp rotates on its fulcrum to push up a press projection, which then clamps the end of the tape that is outside of the area of the band-shaped body and both adhesive faces of the tape together are butt-seemed together.
