  • the channel portion 43 is formed in a manner similar to that shown in FIGS. 1A to 1C , for example.
  • the channel portion 43 may include paper tubes 43b (refer to FIGS. 1D and IE) as tubular bodies.
  • the sheet of the first filter main body 342 is crimped to a greater extent than the sheet of the second filter main body 352. It is preferable that the airflow resistance of the first filter main body 342 be higher than the airflow resistance of the second filter main body 352. The airflow resistance of the first filter main body 342 may be lower than the airflow resistance of the second filter main body 352. It is preferable that the airflow resistance of the first filter main body 342 be, for example, 0 mmH 2 O/mm to 12 mmH 2 O/mm. It is preferable that the airflow resistance of the second filter main body 352 be, for example, 0 mmH 2 O/mm to 12 mmH 2 O/mm
  • the sheet of the first filter main body 342 have an air permeability of, for example, 1000 CU (CORESTA Unit) to 30000 CU after crimp process. It is preferable that the sheet of the second filter main body 352 have an air permeability of, for example, 0 CU to 10000 CU after crimp process.
  • the void volume when the first end surface 346 of the first filter main body 342 is viewed is equal to or greater than the void volume of the acetate filter on the mouthpiece. It is preferable that the area of voids when the first end surface 346 of the first filter main body 342 is viewed be 3 mm 2 or less.
  • the filter 314 has an aesthetic appearance as in the filter 14 described in the first embodiment and the filter 214 described in the second embodiment, and is formed in a state of having appropriate filtration characteristics for the substance such as the flavor substance derived from the flavor source and the aerosol flowing from the tobacco material 312 toward the mouthpiece side end surface 46.
  • the flavor inhalation article 310 that includes the filter 314 formed of a paper sheet.
  • the filter 314 formed of the paper sheet is made of paper, by forming the channel portion 43 in the first filter main body 342 on the mouthpiece side of the filter 314, it is possible to suppress stains on the mouthpiece side end surface 346 of the filter 314 after use, as compared to the acetate filter and the paper filter 114 having no channel portion. Therefore, while the filter 314 according to the present embodiment is made of paper, the appearance after use can be enhanced.
  • the filter 314 formed of a paper sheet, it is possible to control smoking taste (sweetness, smoke volume feeling, stimulation, tobacco feeling (smoking satisfaction), and the like) by appropriately adjusting a material, basis weight, air permeability, crimp depth, void volume, airflow resistance, and the like of the first filter main body 342 and the second filter main body 352.
  • the filter 314 is provided in which the filtration characteristics of the substance such as the flavor substance derived from the flavor source and the aerosol flowing from the tobacco material 312 toward the mouthpiece side end surface 346 during inhalation are appropriately controlled. That is, the flavor inhalation article 310 is provided that includes the filter 314 having suitable filtration characteristics.
  • the filter 314 that is formed of a paper sheet or a non-woven fabric sheet, enhances aesthetic appearance, and has appropriate filtration characteristics, and the flavor inhalation article 310 including the filter 314
  • the channel portion 43 may be formed so as to penetrate through the first filter main body 342.
  • the invention of the present application is not limited to the above-described embodiment, and can be variously modified at the implementation stage without departing from the gist thereof.
  • each embodiment may be carried out in combination as appropriate as possible, and in that case, the combined effect can be obtained.
