According to this, since it is not necessary to embed the capsule 5 in the filter material in the manufacturing process of the filter 4, there is an advantage that the manufacturing suitability of the filter 4 is very excellent.
- releases an internal perfume liquid from the capsule 5 of the filter 4 is arbitrary. The user applies a pressing force to the capsule 5 at the appropriate timing during smoking, after smoking, or before smoking, and crushes the capsule 5 to squeeze the fragrance liquid from the easily breakable portion 55 to the center hole 43a. The fragrance liquid can be contained in the mouth through the center hole 43a.
- the capsule 5 of the present embodiment contains a perfume liquid of 50 mg or more. By securing this amount of the fragrance liquid filled in the capsule 5, the fragrance liquid released from the easily breakable portion 55 of the capsule 5 can be sufficiently supplied into the oral cavity.
- the diameter of the center hole 43a (hollow channel) of the CH filter material 43 is preferably 1 mm or more. If the diameter of the center hole 43a is too small, the fragrance liquid released from the easily breakable portion 55 of the capsule 5 may become difficult to circulate through the center hole 43a, and the center can be smoothly secured by securing the diameter of 1 mm or more.

- the capsule diameter ratio decreases, the above-mentioned center shift amount increases. Therefore, it can be said that it is desirable to set the capsule diameter ratio to be large from the viewpoint of suppressing the center deviation amount between the easily breakable portion 55 in the capsule 5 and the center hole 43a in the CH filter material 43 from increasing.
- the diameter of the capsule 5 is 50% or more of the inner diameter of the cavity section S2 (cavity 42).
- the capsule 5 is easily broken by securing the diameter of the capsule 5 to about 5.8 mm.

- the plasticizer contributes to forming the cellulose acetate fiber tows together into a cylindrical shape. Therefore, in the present embodiment, 19% by mass or more of the plasticizer in the mass of the fibers forming the CH filter material 43 is added to the fibers.
- a relatively larger amount of plasticizer is added to the inner peripheral region facing the center hole 43a (hollow channel) in the CH filter material 43 than to other regions.
- the fluffing of the fiber on the inner peripheral surface of 43a can be more effectively suppressed.
- the axial length of the capsule 5 is shorter than the axial length of the cavity section S2, it is easy to manufacture the filter 4 in which the capsule 5 is accommodated in the cavity 42. Further, since the difference between the axial length of the cavity section S2 (cavity 42) and the axial length of the capsule 5 is set to 5 mm or less, the fragrance liquid discharged from the capsule 5 can be smoothly fed to the center hole 43a of the CH filter material 43.
