The diameter of the hollow part may be 1.0 mm to 5.0 mm. Because the filling density of the fibers of the filling layer 13 is relatively high, air or mist will only flow in the hollow portion during inhalation, and hardly flow in the filling layer 13. In this way, the filterability of the mist in the first central hole section 7 can be reduced. Furthermore, in Figure 2, although the filling layer 13 is provided with a hollow portion, in this embodiment, the hollow portion may not be provided. That is, it is also possible to configure a segment composed of an ordinary acetate filter to replace the first central hole segment.

The filter segment 1 and the first central hole segment 7 are connected by an outer plug wrapper 15. The outer molding wrapper 15 may be cylindrical paper, for example. In addition, the tobacco-containing segment 5, the first cooling segment 6 and the completed filter segment 1 and the first central hole segment 7 are connected by a nozzle liner 16. The connection of these segments can be connected by, for example, coating a vinyl acetate-based paste on the inner surface of the nozzle backing paper 16, and putting the aforementioned three segments in and winding them.
